The Best Shopify Apps for Clothing Stores, Updated Weekly

A clothing store carries two problems a general store barely notices: shoppers order the wrong size and send it back, and nobody can try anything on before they buy. The apps a store installs are how it deals with both. Below are the apps Shopify clothing stores actually run, counted across every clothing store Koala tracks and refreshed every week, followed by our hand-picked apps for the problems clothing sellers face every day.

As of October 12, 2026, the most used app among Shopify clothing stores in Koala Inspector's Shopify Niche Index is Klaviyo: Email Marketing & SMS, installed on 32% of them. The app that sets the niche apart most is BF Size Chart & Size Guide: it runs on 1.8% of clothing stores against 0.7% of all Shopify stores, so it is 2.8x as common here.

Apps that set clothing stores apart

These apps show up in clothing stores more often than across Shopify as a whole, which makes them the clearest clue to what this niche's shoppers expect. The last column is the multiple: 2x means the app is twice as common here as on the average Shopify store.

The 25 most used apps in Shopify clothing stores

How to read the clothing list

Clothing is one of the largest niches in the index, so its most used apps look a lot like Shopify as a whole: reviews, email marketing and the tools nearly every store installs. The signature table is the one to use when you plan your own stack. Size chart apps rank high there, some with a recommender that suggests a size before the shopper reaches the cart, because a wrong size is an expensive return. Print-on-demand apps sit near them, used by brands that sell printed tees and hoodies without holding stock. Color swatches, back-in-stock alerts, a returns platform and SMS marketing fill out the rest.

Several of those categories, size charts and print on demand especially, also show up in our picks below. To see how the biggest clothing brands use them, open a few stores from the top Shopify clothing stores list with the free app detector.

Hand-picked apps for clothing stores

The tables above count what stores run. The picks below are our shortlist for the problems clothing sellers deal with most: sizing returns, stock risk, discoverability, social proof and repeat purchases. Each one fixes a specific problem, so start with the one that matches yours. Plans and prices change often, so check each app's listing for the current plans before you install.

Trendsi: Fashion Dropshipping

Trendsi is a fashion dropshipping app built for clothing retailers. You pick products from its catalog, publish them to your store, and Trendsi picks, packs and ships each order as it comes in. You never hold inventory.

• Developer: ShopSocial, Inc.
• Price: Free plan available, with a paid plan for unlimited listings and bulk import. You pay for the product and shipping when a sale is made.
• App type: Dropshipping and wholesale

App features

• Product import: Add fashion items from the catalog to your store in a click, with a bulk importer on the paid plan.
• Inventory sync: Stock levels sync to your listings, so you are less likely to sell an item Trendsi has run out of.
• Trend-led catalog: New styles are added regularly, which matters in fashion, where what sold well six months ago may not move today.
• Branded fulfillment: Orders ship with your branded invoice, and Trendsi also offers wholesale packs and private labeling.

Pros

• No upfront stock cost, which removes the biggest financial risk for a new clothing store.
• A wide range of women's apparel to choose from.
• Simple setup, with no warehouse or fulfillment to manage.

Cons

• Other stores can list the same catalog items, so your edge has to come from styling, photography and marketing.
• Stock levels and shipping times sit with Trendsi, outside your control.

Who it's for

New clothing store owners who want to test the market without committing to bulk inventory. Also a practical choice for stores that want to add a fashion line alongside print-on-demand products.

Integration with Shopify

Trendsi connects directly to Shopify. Orders sync automatically, and inventory updates feed into your product listings without manual work.

UpPromote Affiliate Marketing

UpPromote is an affiliate and influencer marketing platform. You set commission rates, invite affiliates (influencers, bloggers, existing customers), and the app tracks clicks, conversions and payouts automatically.

• Developer: UpPromote
• Price: Free plan available; paid plans raise the limits and add features.
• App type: Affiliate marketing

App features

• Custom commission structures: Flat or percentage commissions, tiered rates, performance bonuses and product-specific commissions.
• Automated tracking: Referrals are tracked by affiliate link or coupon, so you know which affiliate drove which sale.
• Payouts and reporting: Pay affiliates by PayPal or bank transfer, in bulk or on a schedule, and follow results in ROI reports.

Pros

• Fashion brands often grow through creators and influencers, and UpPromote handles the tracking and payments so you don't need to manage spreadsheets.
• Easy to launch a small program without hiring someone to run it.
• Works with Klaviyo, Mailchimp and Omnisend, plus the Recharge and Appstle subscription apps.

Cons

• The free plan caps monthly referral sales, so a program that takes off moves to a paid plan quickly.
• Building real affiliate relationships takes time. Installing the app is step one, not the whole job.

Who it's for

Small to mid-sized clothing brands that want to test affiliate or micro-influencer marketing without a big budget commitment.

Integration with Shopify

UpPromote connects to Shopify checkout and customer accounts for accurate attribution, and to the email platforms above for affiliate and customer messaging.

Printify: Print on Demand

Printify connects your Shopify store to a global network of print providers. You design the product (t-shirt, hoodie, tote bag), a customer orders it, and Printify routes the order to a provider who prints and ships it.

• Developer: Printify
• Price: Free plan available; a Premium plan lowers product costs for higher-volume stores. Product and shipping costs are billed only when you make a sale.
• App type: Print on demand

App features

• Large product catalog: Apparel basics like t-shirts and hoodies, plus accessories and home goods.
• Design tools: The Product Creator and mockup generator let you upload artwork and preview it on the product.
• Provider choice: For most products, you pick which print provider fulfills the order. Providers vary by location, price and print quality.

Pros

• No minimum order quantities. A customer can order one item and it gets printed and shipped.
• Useful for testing designs before committing to larger inventory buys.
• Premium's product discounts improve margins on higher-volume stores.

Cons

• Fulfillment times vary by provider. If a customer in Germany orders from a US-based printer, shipping adds days compared to a European provider.
• Not every blank item supports every placement or printing method.

Who it's for

Clothing store owners who want to sell custom-designed apparel, especially brands built around original artwork or niche designs.

Integration with Shopify

Orders from your Shopify store pass straight to Printify for fulfillment, with order handling automated.

Kiwi Size Chart & Recommender

Size returns are one of the costliest problems in online clothing retail. Kiwi adds size charts to your product pages and suggests the right size to each shopper before they buy.

• Developer: Staytuned
• Price: Free plan for a few size charts with Kiwi branding; paid plans unlock more.
• App type: Size charts and recommendations

App features

• Custom size charts: Build charts to your own garment measurements, starting from a ready-made template if you like, so they match your supplier's actual sizing.
• Fit recommendations: The app suggests a size to each shopper, which cuts the guesswork that leads to sizing returns.
• Flexible placement: Show charts on product pages or collection pages, wherever they help most.

Pros

• Helps cut returns from wrong-size orders, which saves on reverse shipping.
• Gives shoppers confidence to buy items where fit is tricky, such as fitted dresses, jeans and activewear.
• Quick to add to existing products with no coding required.

Cons

• Setup takes time. Building accurate charts for every product category in your catalog is not instant.
• Recommendations are only as good as the measurements you enter.

Who it's for

Any clothing store that sells items where fit matters. Particularly useful if you dropship or use print on demand, where sizing varies by supplier.

Integration with Shopify

Charts display alongside product variants without disrupting the rest of your page layout.

Smart Product Filter & Search

Shopify's built-in filtering is limited. Smart Product Filter & Search from Globo adds attribute filters (size, color, material, price range) and a search box with autocomplete and typo tolerance.

• Developer: Globo.io
• Price: Paid plans; a free tier covers setup and testing before you go live.
• App type: Search and navigation

App features

• Attribute filters: Shoppers filter by size, color, price, vendor, tag or any custom field you set up.
• Search with suggestions: Results appear as shoppers type, with typo tolerance and synonyms. Someone who searches for "blous" still finds blouses.
• Layout control: Sidebar, dropdown or mobile menu styles, with colors and fonts to match your store.

Pros

• Clothing stores with large catalogs need this. Without good filters, a customer looking for a size 12 burgundy dress leaves empty-handed.
• Better search tends to lift conversion directly.
• Search and filter reports show what shoppers are looking for.

Cons

• Some advanced filter setups are locked to higher-tier plans.
• New products and tags need upkeep so the filters stay accurate.

Who it's for

Clothing stores with more than a few dozen products. The bigger the catalog, the more this pays off.

Integration with Shopify

Search reports show what customers look for, so you can adjust your catalog or your filter structure to match.

Rise Gift Cards & Store Credit

Rise.ai handles gift cards, store credit and loyalty rewards in one app. Customers earn credit, and that credit brings them back. Gift cards work as both a revenue tool and a way to move seasonal stock.

• Developer: Rise.ai
• Price: Paid plans, each with a free trial.
• App type: Gift cards and loyalty

App features

• Branded gift cards: Digital, physical and reloadable cards with your branding, custom amounts and gift messages. A card sent as a gift can bring a new shopper to your store.
• Store credit and rewards: Issue credit for sign-ups, referrals and VIP tiers, and run reward and cashback programs.
• Refunds as credit: Offer store credit in place of a cash refund, which keeps the money in your store.

Pros

• Gift cards suit fashion around birthdays and holidays, when the giver doesn't know the recipient's size or style.
• Loyalty credit reduces churn. Customers with an outstanding balance have a concrete reason to come back.
• Store credit refunds keep revenue in the business when a garment comes back.

Cons

• No permanent free plan, so it becomes a paid commitment once the trial ends.
• Loyalty programs take time to show results. Don't expect a lift in retention in the first month.

Who it's for

Clothing stores focused on repeat customers rather than single-purchase sales. Works well for stores with a strong brand identity.

Integration with Shopify

Works with Klaviyo, Attentive, Gorgias, Loop Returns and Shopify POS, so balances and rewards can show up in your emails, your returns flow and your physical store.

Yotpo: Product Reviews App

Yotpo automates review collection after purchase and displays the reviews on product pages. It also collects customer photos and videos, which carry weight in fashion because shoppers want to see how garments look on real bodies.

• Developer: Yotpo
• Price: Free plan for low order volumes; photo and video reviews and Google rich snippets come with paid plans.
• App type: Reviews and UGC

App features

• Automated review requests: Emails customers after their order, using a library of templates.
• Photo and video reviews: Customers can attach images and clips, which tell a fashion shopper far more than star ratings alone.
• Rich snippets: Review data can show star ratings in Google search results.
• Social sharing: Reviews and customer content can be displayed on social media.

Pros

• Reviews with photos answer the main worry in online clothing: "will it look like the picture?"
• Reviews compound over time. A product page with hundreds of reviews converts better than one with a handful.
• Moderation tools let you respond to negative feedback before it sits unaddressed.

Cons

• The free plan covers only a small number of orders a month, and collecting photos and videos needs a paid plan.
• Someone needs to watch incoming reviews. An ignored negative review hurts more than the review itself.

Who it's for

Fashion stores that want to build credibility through customer proof rather than brand-only marketing.

Integration with Shopify

Works with Klaviyo for post-purchase flows and with Instagram for social content.

Upsell & Cross Sell - AW

Upsell & Cross Sell by Aheadworks shows product recommendations at several points in the shopping journey: product pages, the cart, checkout and the thank-you page. In fashion, that means suggesting matching items (a belt with jeans, a scarf with a coat) rather than random related products.

• Developer: Aheadworks
• Price: Free plan with limited placements and clicks; paid plans add more of both.
• App type: Upsell and cross-sell

App features

• AI-assisted product recommendations and "frequently bought together" pairings
• Placements on product pages, the cart and mini-cart, checkout, and post-purchase pages
• One-click add-to-cart on every recommendation
• Analytics showing click-through and conversion rates for each recommendation

Pros

• Clothing is well suited to cross-selling. A shopper who buys a dress is a good candidate for a bag or jewelry in the same style.
• Several placements let you test where recommendations perform best in your store's flow.
• No coding required to set up.

Cons

• The free plan limits placements and monthly clicks and shows app branding, so a growing program means upgrading.
• AI recommendations improve with order history, so a new store gets less relevant suggestions at first.

Who it's for

Clothing store owners who want to raise average order value by suggesting genuinely related items rather than random top sellers.

Integration with Shopify

Adds recommendation blocks to your store's pages without custom code.

Loox - Product Reviews App

Loox focuses on photo and video reviews. After purchase it emails customers and can offer a discount in exchange for a review with a photo, an incentive that tends to bring in more photo reviews than a plain request.

• Developer: Loox
• Price: Free plan available; paid plans, each with a free trial, add video reviews and syndication to Google, Meta and TikTok.
• App type: Reviews and testimonials

App features

• Photo and video review collection through automated emails, QR codes and discounts
• Discount incentives for customers who add a photo to their review
• Customizable widgets that show reviews as galleries, carousels or snippets on product pages
• Review syndication to Google Shopping on paid plans

Pros

• Fashion shoppers rely on seeing real people in the garments. A photo from someone with the same body type as the shopper persuades more than any studio shot.
• The discount incentive brings the reviewer back for a second purchase.
• Quick to set up, with automatic review collection.

Cons

• Video reviews and syndication sit on paid plans.
• Discounts for photos cost margin, so set the incentive with care.

Who it's for

Clothing stores that want to build a library of customer photos to use on product pages and across social channels.

Integration with Shopify

Integrates with Klaviyo and Omnisend for email and SMS.

EM Lookbook Gallery

This app lets you build styled photo galleries with products tagged directly in the image. A customer browsing a lifestyle photo of a full outfit can click any item, or add it straight to the cart.

• Developer: Expert Village Media Technologies
• Price: Free plan for one gallery; paid plans, each with a free trial, add more.
• App type: Images and media

App features

• Galleries with product hotspots linked to your Shopify catalog
• Add-to-cart directly from the image
• Collage, slideshow, carousel, masonry and grid layouts
• Galleries generated automatically on product pages
• Mobile-friendly layouts

Pros

• Fashion stores sell looks as much as individual items. A lookbook presents full outfits and raises the number of items per order.
• Shoppers who arrive from Instagram or Pinterest already know this way of browsing.
• No coding required to set up.

Cons

• The free plan covers only one gallery.
• On a large catalog, tagging every product in every image takes manual work.

Who it's for

Fashion and lifestyle stores that invest in photography and want to show products in context instead of as isolated shots.

Integration with Shopify

Links straight to your Shopify catalog and works with PageFly pages.

Nudgify Social Proof Sales Pop

Nudgify shows real-time social proof on your store: how many people are viewing, recent purchases and low-stock warnings. It is the online version of a queue outside a shop.

• Developer: Nudgify
• Price: Free plan with a monthly impression cap and Nudgify branding; paid plans raise the limits.
• App type: Social proof

App features

• Live visitor counts and recent purchase notifications
• Low-stock alerts that create real urgency when inventory is actually limited
• Review nudges that surface customer ratings
• Custom layouts and an editor to style the nudges

Pros

• Low-stock nudges suit fashion, where limited sizes and colorways are a real constraint.
• Simple to install.
• Works across store sizes.

Cons

• The free plan caps monthly impressions and shows Nudgify branding.
• Overused urgency notifications feel pushy. Tune their frequency and placement.

Who it's for

Clothing stores that want to reduce cart abandonment by showing real demand at the moment a shopper is deciding.

Integration with Shopify

Runs alongside your theme and your other marketing apps.

QuickSync for TikTok Shop

QuickSync connects your Shopify catalog to your TikTok Shop. Products and stock stay in step, and orders placed on TikTok flow back into Shopify.

• Developer: R. I. T. N. S.
• Price: Paid plans with a free trial; product and order sync need the Pro plan or higher.
• App type: Social commerce

App features

• Product sync from Shopify to TikTok Shop
• Order sync that brings TikTok orders into Shopify
• Inventory sync on every plan to prevent overselling

Pros

• Clothing is made for short video, and TikTok Shop lets viewers buy straight from it.
• Removes the manual work of keeping two catalogs in sync.

Cons

• Limited to TikTok. If you also sell on Instagram or Pinterest, you need separate tools for those channels.
• The entry plan covers inventory only, so most stores will need Pro.

Who it's for

Clothing store owners who already make TikTok content, or plan to, and want to sell to that audience without sending them to a separate site.

Integration with Shopify

Syncs directly with Shopify's product catalog and order management.

Where to start

You don't need every app on this page. Start with the one that fixes your biggest current problem. If returns are eating your margins, a size chart app such as Kiwi comes first. If you are trying to grow an audience, start with UpPromote or QuickSync. If trust is what holds back conversion, Loox or Yotpo will do more than anything else here. Then come back to the tables at the top of the page: they refresh every Monday, so a tool spreading through clothing stores will show up there.

Koala Inspector is a free Chrome extension that shows you which apps any Shopify store runs, along with its theme and its best-selling products, so you can see what your competitors chose before you commit to a tool. Try it free.
