Fashion & Apparel A/B Tests: Real Results and What to Test First

A typical fashion ecommerce store converts about 1.5% to 2% of sessions into orders.

IRP Commerce's UK benchmark put fashion, clothing and accessories at 1.62% in September 2026, below the 1.97% average across all the markets it tracks.

The fashion tests in our database show the gap closing fastest when stores answer fit and sizing questions and make products easier to find on mobile.

This guide covers the clothing, footwear, swimwear, underwear, socks and jewelry tests in LiftArchive: what fashion buyers need, what won and lost, and what to test first.

The full grid of matching tests is shown above this text.

Clothing store conversion rate: what's normal

Fashion converts below the ecommerce average in most benchmark sets, and the reason is simple.

Shoppers browse a lot, compare across tabs and buy only when they're confident about fit. Many sessions are window shopping.

IRP calculates conversion rate as transactions divided by sessions, using trading data from independent merchants on its platform.

So treat it as a reference point for small and mid-sized stores, not a target.

Your own rate depends on price point, traffic mix and how much of your traffic is returning customers.

Our ecommerce conversion rate page explains why benchmarks from different sources disagree.

Conversion rate is also the wrong scorecard on its own in fashion.

A test that raises orders but also raises returns can lose money.

The NRF and Happy Returns 2024 report estimated that 16.9% of US retail sales were returned that year, and 51% of Gen Z shoppers said they buy several items intending to return some.

Track revenue per visitor during the test and check return rates for the cohort afterwards.

Apparel ecommerce CRO: what fashion buyers need

Fashion shoppers can't try anything on. Most tests that won in our database settled one of three questions.

• Will it fit me? Size guides, model measurements and size filters.
• Can I find what I want fast? Search, menus and filters, mostly on mobile.
• Does it look as good as the photo? Zoom, detail views, reviews and fabric information.

Price and offers matter, but the tests below suggest fashion shoppers are less price-sensitive than many store owners assume.

Fit and sizing: the strongest pattern

Fit answers often win because they remove the main reason to hesitate.

GrowthRock moved an apparel store's size guide link from inside the product description to just above the size dropdown.

That lifted conversion rate 21%, with +22% average order value and +46% revenue per session.

The agency itself flags the result as fragile: under 200 conversions per variation, stopped at 96% significance after 10 days.

Dave Diederen tested a model size line on product images, such as "Elly is 5'8\" and wears a size S."

It raised revenue per visitor 4.61%. That's a small, believable lift for a change that takes an afternoon to build.

Size works in navigation too. In an anonymized Optimizely summary, a footwear retailer merged separate men's and women's size filters into one and moved it above the fold.

Size filter use rose 33.8% and revenue per visitor rose 2%, which the vendor put at about $12.7M a year.

More ideas are in our variant selector tests.

Search, menus and filters on mobile

Fashion catalogs are big, and most fashion traffic is on phones.

Several of the larger wins in our database came from helping mobile shoppers narrow the catalog.

• Dorado Fashion found 30% of mobile visitors tapped the search icon but only 1% searched. A focused search screen with popular searches lifted conversion 26.55% over 33 days (credited to VWO).
• Andaaz Fashion added predictive search suggestions and increased purchases 18.39% (ConvertPolo).
• Featsocks made its mobile search bar clearer and gained 18.73% more orders (Conversion Fanatics).
• Utsav Fashion showed sub-categories in the mobile menu and raised purchase conversion 11.58% (VWO).
• Blend Commerce simplified an apparel brand's mobile menu and lifted revenue per visitor 11.11%.

Not every navigation idea worked. GrowthRock's category link bar on a mobile homepage showed +5% orders but was inconclusive.

See our filters and search and navigation menu pages for tests from other categories.

Navigation also featured in the biggest case study here.

Oliver Kenyon combined a mega menu, collection filters and tiered cart rewards for the tattoo-inspired apparel brand Sullen, worth +$337,203/month.

Because several changes shipped together, it tells you the package worked, not which part did.

Product pages: images, reviews and detail

Product page tests in fashion mostly help shoppers judge the garment.

• Conversion Fanatics turned on image zoom for a clothing store and reported +84.7% conversions. The same report gives +2% add to cart and +14% completed carts, and no sample size, so treat the headline number with caution.
• Andaaz Fashion put tabs for product details, delivery and support on the mobile product image area. Purchases rose 125.95%, again without a published sample size.
• GrowthRock added a star rating summary at the top of product pages: +15% conversion rate at 94% significance, with no change in add-to-cart rate.
• Blend Commerce tested a review carousel (+4.21% conversion rate), an accordion for long product info (+9%) and a sticky add-to-cart button (+16.27%).
• ConvertPolo added benefit bullets to a socks product page and raised conversion rate 18.16%.

Vasta's bundle of five trust signals beside add-to-cart reported +22.95%, but as a bundled change it can't isolate which signal mattered.

Price, discounts and offers

Two brands tested higher prices and saw no drop in conversion.

Minnow raised prices 10% on swimwear best sellers and conversion held steady, though no figures were published.

SAXX raised one underwear collection 5% for four weeks and found no significant change in conversion.

If you're discounting by default, a price test may be worth more than another layout test.

Discount framing gave mixed results. GrowthRock's "You Save #%" label showed no change when every product had the same discount.

When discounts varied, percent-off labels lifted conversion 2.57%.

A full-width percent-off banner on a shoe retailer's sale items raised purchase conversion 19% (Swanky).

Cart offers can work when they're tied to the next item.

Dorado Fashion's "1 product away from an extra 30% off" message in the mini cart increased purchases 14.14%.

Free gifts did less: Clean Commit's message that every shoe order includes free socks moved conversion -0.6%, with a 46.7% probability to beat control.

Guided selling helped in accessories and custom products.

Featsocks turned its Mystery Box into a single quiz page and got 21% more orders, and a clothing store's build-your-own box options lifted conversion 35% (both Conversion Fanatics).

A German jewelry brand showed shoppers a preview of their uploaded photo in the cart and raised cart-to-checkout 5% (ABConvert).

When a product is personal, showing the shopper what they'll get reduces doubt.

What lost or did nothing

Losses and flat results are where fashion stores save the most time.

• A head-to-toe outfits carousel on an apparel homepage cut add to cart 6.07% and click-through 10.4% (Optimizely). Broad merchandising pulled shoppers away from the products they came for.
• Quick shop on GrowthRock's collection pages produced more add-to-carts but no more orders, across hundreds of thousands of visitors. Adding to cart is not buying.
• Blend Commerce's simplified homepage hero won 26% on desktop but mobile conversion and revenue fell, so it shipped on desktop only. Always split results by device.

Be careful with the biggest numbers in this category.

Results such as Conversion Fanatics' pink add button (+57%) come without sample sizes.

Large lifts from small stores often shrink when retested, a pattern explained in our winner's curse guide.

What to test first on a fashion store

1. Move fit help next to the size selector. Size guide links, model height and size worn, and fit notes. Cheap to build and the most consistent pattern above.
2. Fix mobile search and menus. Check how many mobile visitors tap search versus actually search, as Dorado Fashion did.
3. Surface reviews and ratings near the top of product pages.
4. Test price before discounts. Two fashion brands raised prices without losing conversion.
5. Measure revenue per visitor and returns, split by device. Fashion wins on desktop can lose on mobile.

Smaller stores should test bigger, bolder changes and run them for full weeks; our low-traffic testing guide covers how.
