Every clothing brand knows the parcel that comes back with a note saying "too small". Returns eat the margin on the sale, the shipping both ways and the time to inspect, steam and restock the piece, and a garment that misses a season may never sell at full price again. This guide covers how to reduce returns for a clothing brand or online fashion store: why clothes come back, ten fixes that work, the size and fit tools worth knowing, and what to measure.
Most of it comes down to one idea: a shopper who knows what will arrive, and in which size, rarely sends it back. Everything below helps them know before they pay.
How to reduce returns in one minute
- Publish garment measurements for every size, not only a generic size chart.
- Add a fit note and the model's height and size to every product.
- Offer a size recommender or fit quiz on the product page.
- Answer size questions in chat before the order, on Instagram, WhatsApp and your website.
- Show fabric, stretch, drape and true colour in photos and video.
- When a shopper wants to order two sizes, help them choose one.
- Offer an exchange before a refund, and make it easy.
- Record a reason for every return and fix the product page it points to.
- Fix the products that come back most, size by size.
- Try virtual try-on where the look, not the fit, is the doubt.
Why clothes get returned
Retail returns are large in every category, and online orders come back more often. The National Retail Federation and Happy Returns estimate that 15.8% of US retail sales, $849.9 billion, would be returned in 2025, and 19.3% of online sales.
Clothing runs higher still, and the reason is mostly fit. Coresight Research estimates the average US online apparel return rate reached 23.4% in 2025, and nearly 70% of shoppers who returned clothing bought online said size and fit was the reason. McKinsey's 2021 survey of North American apparel retailers put it at about the same share: 70% of returns were caused by poor fit or style.
The NRF report also names "bracketing", ordering several sizes and sending back the ones that don't fit, among the costly return habits close to two-thirds of shoppers admit to. Bracketing is a fit problem too: shoppers do it because they can't tell which size will fit.
| Why it comes back | What prevents it |
| Too small or too big | Garment measurements, fit notes, a size recommender, a size question answered in chat |
| Fit or cut not as expected (tight across the shoulders, short in the body) | Fit notes per product, the model's height and size, photos from the side and back |
| Fabric, colour or quality not as pictured | Close-up fabric shots, video, the colour named plainly, stretch and lining stated |
| Ordered two sizes to try both | Help choosing one size before checkout; easy exchanges |
| Arrived too late for the occasion | A delivery date before checkout, answered in chat when asked |
| Changed their mind | Hard to prevent; a clear policy keeps it cheap |
10 ways to reduce returns for a clothing brand
1. Publish garment measurements, not only a size chart
A generic chart says what a "medium" body measures. A shopper needs to know what this garment measures: chest, waist, hip, length, sleeve and inseam for each size, flat or around. Put them on the product page, in centimetres and inches if you sell abroad, and say how to measure a garment they already own and love. It is the single most useful thing you can add, and it costs nothing but a tape measure.
2. Add a fit note and the model's size
One line per product does a lot of work: "Runs small, size up", "Relaxed fit", "True to size, no stretch". Add the model's height and the size they wear. When the same block or pattern runs small every time, say so on every product cut from it.
3. Offer a size recommender or fit quiz
Size recommenders ask the shopper a few questions (height, weight, usual size in another brand, how they like things to fit) and suggest a size. On Shopify they range from free size-chart apps to enterprise tools; the table further down compares them. They work best on the website product page, where the shopper is already looking at the garment. In a 2023 Coresight Research survey of US apparel brands and retailers, size and fit was the top reason given for online returns, and 80% of those that already had a size recommender said it increased conversion.
4. Answer size questions in chat before the order
Many shoppers would rather ask. "I'm 5'4 and usually a 10, which size?" is one of the most common messages a clothing brand gets on Instagram and WhatsApp, and a shopper who gets no answer either buys two sizes or buys the wrong one. Reply fast, from the garment's measurements and fit note, and ask one question back when you need it ("Do you like it fitted or loose?").
This is where an AI sales agent helps. TailorTalk reads your catalogue and size charts and answers size, fit, stock and delivery questions in Instagram DMs, WhatsApp and website chat at any hour, then hands the chat to your team when a question needs a person. Our guide to fashion product recommendation chatbots shows how size advice in chat works in detail.
5. Show fabric, drape and true colour
Fabric and colour surprises are the next biggest reason after fit. Shoot the fabric close up, show the garment from the side and back and on a moving body, say whether it stretches and whether it is lined, and name the colour plainly ("dusty pink, not baby pink"). If a shopper asks for a real-light photo in the DMs, send one: it costs a minute and saves a return.
6. Help shoppers choose one size instead of two
A cart with the same dress in two sizes is a return you can see coming. In chat, the moment a shopper says "I'll order both", answer with the measurements that settle it. Don't refuse the order; just make the second size unnecessary.
7. Offer an exchange first
An exchange keeps the sale, a refund loses it. Offer a free or cheap size swap ahead of a refund, ship the new size as soon as the return is on its way, and make the steps clear in one message. Your return policy must still meet the law where you sell: our customer service guide for clothing brands covers the UK, EU and US rules and has reply templates for returns and exchanges.
On Shopify, self-serve returns let customers ask for a return from their order status page without messaging you, within the return rules you set, including whether return shipping is free. Shopify launched it in 2023 as a free tool; you switch it on in your admin, and it needs the new customer accounts.
8. Record a reason for every return
Ask for a reason on every return, from a short fixed list: too small, too big, fit not as expected, fabric, colour, quality, late, changed mind. Then read it by product and by size each week. Ten "too small" returns on one dress is a product page to fix, not bad luck.
9. Fix the products that come back most
A few styles usually cause most returns. Sort returns by product and size, and for the worst ones change the fit note, the size chart, the photos, or the pattern itself. Chat logs are useful here too: the questions shoppers ask before buying a style show what the page fails to say.
10. Use virtual try-on where the look is the doubt
Virtual try-on shows how a style or colour looks on the shopper. It helps with "will this suit me" more than "will this fit me", so pair it with measurements. Our guide to virtual try-on for clothes covers how it works and which Shopify apps offer it.
Size and fit tools for online clothing stores
Yes, there is AI that answers size and fit questions for an online clothing store, in two forms. Size recommenders sit on the product page and suggest a size from a short quiz. AI sales agents answer the question in chat, in the shopper's own words, on the channels where they message you. Many brands use both.
| Tool | What the shopper gets | Where it works | Price (as listed) |
| Smart Size Chart & Size Guide (SmartSize) | Size charts, a true-to-size fit scale and, on Pro, an AI fit quiz | Shopify store | Free (2 charts); $9, $12 and $19 a month |
| Fit Quiz: Size Recommender (Easysize) | A size quiz that needs no measurements | Shopify store | From $29 a month, plus $0.15 per item added to cart with a quiz recommendation |
| Kiwi Size Chart & Recommender | Size charts on the product page and, on paid plans, a size recommender | Shopify store | Free (3 charts, watermark); $7.99, $14.99 and $26.99 a month, the top two plus order-volume charges |
| TailorTalk | An AI sales agent that answers size, fit, stock and delivery questions in the chat, from your catalogue and size charts | Instagram DMs, WhatsApp, website chat | From $49 a month; 7-day free trial |
Larger brands also look at True Fit and Fit Analytics, which recommend sizes from purchase and return data across many brands. Neither publishes prices; both sell through a demo. Fit Analytics, owned by Snap from 2021 to 2024, is independent again.

What to measure
- Return rate, overall and by product, by size and by channel.
- Return reasons, as a share of all returns.
- Exchange share: exchanges as a share of all returns. Higher is better.
- Orders with two sizes of the same item.
- Size questions answered in chat, and the return rate of orders that asked one.

What is a normal return rate for clothing?
Clothing has one of the highest return rates in retail. Coresight Research estimates the average US online apparel return rate at 23.4% in 2025, against 19.3% for online sales across all categories (NRF and Happy Returns). Rates vary a lot by category: fitted dresses and jeans come back more than T-shirts and scarves.
What is the main reason clothes are returned?
Size and fit. Nearly 70% of shoppers who returned clothing bought online gave size and fit as the reason (Coresight Research, 2026), and McKinsey's survey of apparel retailers put 70% of returns down to poor fit or style.
How can I reduce returns in my online clothing store?
Publish garment measurements and fit notes, offer a size recommender, answer size questions in chat before the order, show fabric and colour clearly, help shoppers pick one size instead of two, offer exchanges first, and record a reason for every return so you can fix the products that come back most.
Is there an AI that can answer size and fit questions for an online clothing store?
Yes. Size recommender apps suggest a size on the product page from a short quiz, and AI sales agents such as TailorTalk answer size and fit questions in Instagram DMs, WhatsApp and website chat from your size charts and catalogue, then hand over to your team when needed.
Does a size chart reduce returns?
A generic size chart helps a little. Garment measurements for each size, a fit note and the model's size help much more, because they tell the shopper how this particular piece fits.
