How to Reduce Returns on a Shopify Fashion Store

She has a wedding in three weeks and can’t tell from the size chart whether she is a 10 or a 12 in this dress. So she orders both. The 12 fits, and the 10 goes back in its bag with a printed label. You shipped two dresses to sell one, and the one that comes back has to be checked, steamed and restocked before it can sell again.

Return rate is the share of what you sell that comes back. In a fashion store most returns are decided before the order is placed: the shopper guessed her size, or bought two to be safe. It is the fifth of six stages in a Shopify fashion store, after AOV, where the order grows, and before Repeat Purchase, where she comes back to buy again.

This hub covers what to measure, what a normal number looks like, why clothes come back, and the four guides that help shoppers order the right size the first time, three of them with Shopify’s own tools.

What is return rate for a Shopify fashion store?

Return rate is the share of what you sell that comes back: in Shopify, the units physically returned divided by the units ordered, read product by product.

One number tells you how much comes back. The reasons behind it tell you which fix to try first, and in fashion most of those reasons are about size.

A return costs more than the refund. You already paid to bring the shopper in and ship the order, you often pay the return postage, and the piece is off sale until it is checked and restocked.

What is a good return rate for a fashion store?

Nearly a quarter of clothing bought online in the US comes back, so a good target is a rate below your own starting point, for your own mix of products.

Two more benchmarks give an all-category view and a UK fashion view.

No independent benchmark covers fashion stores on Shopify alone yet. Your rate also depends on what you sell: fitted pieces, where size is hard to judge, give shoppers more reasons to send them back than scarves or jewellery do.

Why do shoppers return clothes they bought online?

Most clothes come back because the shopper had to guess her size or how the piece would look on her, and the guess was wrong.

She had to guess her size

Sizes differ from brand to brand, and many size guides don’t help. In Baymard Institute’s testing, only 17% of desktop apparel sites and 13% of mobile sites gave shoppers enough size information (Baymard Institute, 2022). A generic chart for the whole store, with no note on how this piece fits, leaves her guessing.

She ordered two sizes to be safe

Bracketing means ordering several sizes or colours of one piece and returning the rest. In a 2025 survey of 1,002 UK shoppers, 62% said they had bracketed, and ordering more than one size was the most common form (fulfilmentcrowd, 2025). Bracketing is a shopper’s own fix for a size she can’t judge. Give her a size she trusts, and she has less reason to order two.

It fit the model, not her

One photo on one model in one size shows how the piece falls on that body. Without the model’s height and size, or reviews from buyers with a body like hers, she can’t translate it to her own.

The colour or style didn’t suit her

Some pieces fit and still come back: the colour looked different on her, or the style wasn’t right for her occasion. These are doubts the product page has to answer before the order, and the Conversion Rate hub covers them.

She had nothing to wear it with

A statement piece with no partner in her wardrobe can hang with its tags on until the return window is nearly closed, then go back. Showing what to wear it with, as the AOV hub explains, gives it a place in an outfit.

Some reasons are not about styling

Damaged or wrong items, late deliveries and returns abuse need operational fixes, not styling. NRF and Happy Returns found that 9% of all returns are fraudulent (2025). A clear returns policy, shown on the product page, helps with these too.

Which pattern shows up in your return reasons?

Each pattern points to a different first fix.

Which fixes reduce returns?

Four guides cover this stage: give each piece its own size guide, add a fit note, show the model’s size with buyers’ fit reviews, then add personal size and fit advice for every shopper.

Each guide is one Return factor in the free Styling Score. DIY styling guides use Shopify’s own tools; the AI styling guide adds a personal AI stylist.

Which fix should I start with?

Start with a size guide and fit notes on your most-returned pieces: they cost nothing, and every other fix builds on the facts they hold.

Is a returns app enough to cut returns?

No: a returns app makes each return faster and can turn a refund into an exchange, but it acts after the order, when the wrong size has already shipped.

Use both. Prevention cuts how many returns happen; a returns app makes the rest cheaper to handle, and an exchange keeps the sale.

What does a personal AI stylist add before checkout?

iWAND is our product.

iWAND is an AI stylist for independent fashion brands on Shopify. Its styling agents give every shopper personal outfit, fit and styling advice from the brand’s own catalogue. It is free to install, and brands pay 5% only on sales iWAND makes.

Before checkout, five agents help a shopper order the piece she keeps:

• Size asks her height, usual size and how she likes clothes to fit, then names her size in that piece.
• Consult answers whether the colour works with her colouring and whether the piece suits her occasion, and suggests a better piece from your catalogue when the honest answer is no.
• Refine swaps the colourway or one detail, such as a longer hem, and keeps the rest of the look.
• Try-On shows the outfit on a model matched to what she described, so she can judge the look before she buys.
• Pair lets her upload a photo of a piece she already owns, then builds a complete outfit around it, so the new piece has something to be worn with.

A return is a styling decision that happened in the customer’s bedroom instead of on your product page.

Bagher Ahmadi, co-founder and CEO of iWAND, 2026

Judge it on your own catalogue, not on a demo: size advice is only as good as the measurements and fit facts in your product data, which is why the DIY guides above help it too.

How do I measure return rate in Shopify?

Record your returned quantity rate and return reasons for orders whose return window has closed, fix your most-returned products first, then compare a later period the same way.

1. Set your baselineIn Shopify, open Analytics › Reports and find returned quantity rate and return line item reason in the sales reports. Pick a month of orders older than your return window, so all its returns have arrived.
2. Rank your productsBreak returned quantity rate down by product. Fix the pieces that sell often and come back often first.
3. Read the reasonsSince January 2026, Shopify suggests return reasons that fit the product, such as too big and too small for apparel. Count how many returns on each top product are about size.
4. Change one thingAdd one fix to your ten most-returned products first, so the change is big enough to show in the numbers.
5. Compare once the window closesCompare orders placed after the fix with your baseline, once their return window has closed. Count exchanges separately: a return turned into an exchange still keeps the sale.

Small changes in return rate move real money. A store that ships 1,000 pieces a month at $60 each and gets 25% back returns $15,000 of goods a month; at 20% it returns $12,000, so $3,000 a month stays sold, before return postage and handling. This is arithmetic, not a measured result.

Where do returns fit in the six stages?

Return is the fifth of six stages: it decides whether the order that AOV grew stays kept, and a shopper whose order fit is the one who comes back for Repeat Purchase.
