Return fraud in fashion ecommerce is real, expensive, and smaller than most board decks assume. The direct answer: retailers estimate that 9% of returns are fraudulent, which means more than 90% come from customers who simply could not tell whether the item would fit. This post separates deliberate abuse from honest uncertainty, and explains why the second category is where the margin actually sits.
What Return Fraud Costs Fashion Ecommerce
US consumers were expected to return close to 850 billion dollars of merchandise in 2025, with online returns running at 19.3% of online sales. Retailers put the fraudulent share of those returns at 9%, which is a very large absolute number attached to a fairly small percentage.
In the UK, serial returners accounted for an estimated 6.6 billion pounds of online returns across non-food retail in 2024, and fashion carries a disproportionate share of that volume. The share of shoppers classified as serial returners then fell from 12% to 8% as retailers tightened policies, which tells you the behaviour responds to incentives.
The per-item economics are what turn this into a P&L problem. Processing, inspection, restocking, and markdown risk stack up on every returned garment, a cost we break down in The True Cost of Fashion Returns. Fraud makes those costs unrecoverable, because the item often comes back unsellable or does not come back at all.
Wardrobing, Bracketing and Serial Returning Are Three Different Problems
Most returns-abuse programmes fail because they treat one metric, return rate, as one behaviour. It is at least three, and only one of them is unambiguous fraud.
Wardrobing
Wardrobing means buying an item, wearing it once for an event, and returning it for a refund. Around 16% of UK shoppers admit to it, rising sharply among under-35s. This is the behaviour that fits the legal definition of return fraud, and it concentrates in occasionwear, formalwear, and premium outerwear.
Bracketing
Bracketing means ordering the same item in 2 or 3 sizes and returning the rest. It is not fraud, it is a rational response to a size chart the shopper does not trust, and it is covered in detail in Size Bracketing: Fashion Ecommerce's Hidden Return Driver. Penalising it punishes customers for a problem the retailer created.
Serial returning
Serial returners sit in the middle. Some are abusing the policy, and some are simply high-frequency buyers in a category where they cannot judge fit online. Before any account gets flagged, the reason codes need to tell you which one you are looking at.
Why Return Fees Are a Blunt Instrument
The industry response so far has been to charge. Roughly two thirds of fashion retailers now charge for at least one return type, Zara applies a 1.95 pound fee on UK online returns, and several marketplaces have added per-customer fees or account deactivation for the worst offenders.
Fees do work on the abusive tail, because wardrobing is price sensitive by definition. The problem is that a returns fee is applied to everyone, and the honest majority, more than 90% of returns, gets taxed for a fit problem the product page failed to solve.
That has a measurable cost on the front end. Fit uncertainty is already the leading reason fashion shoppers abandon carts, and adding a charge for getting the size wrong raises the cost of trying, which is exactly the decision a hesitant shopper is trying to avoid making. Policy tightening is a margin lever with a conversion bill attached, and most retailers never measure the second half.
Shrink Honest Returns First, Then Police What Is Left
The sequence matters. If 9 out of 10 returns are honest, and roughly 60% of fashion returns are driven by fit and appearance, then the biggest available win is removing the uncertainty, not punishing the outcome.
A practical order of operations:
- Instrument the reason codes. Split "too small", "too big", "looks different", and "changed my mind" into separate buckets. Without this split you cannot tell fraud from a bad size grid.
- Resolve fit and colour before checkout. Virtual try-on, a size recommendation mapped to your own grid, and a colour profile answer the three questions that drive the honest 90%, as covered in AI Size Recommendation: Fixing Fashion's Biggest Return Driver.
- Segment by cohort, not by rate. Compare return rate and reason mix for shoppers who used the fit tools against those who did not, over a full 90-day window.
- Apply friction narrowly. Once honest returns fall, the remaining high-return accounts are a much cleaner signal, and account-level action becomes defensible instead of scattershot.
Done in that order, the fee conversation gets easier, because it applies to a smaller and better-identified group. Done in reverse, you cut returns and conversion at the same time, which is a wash at best.

Frequently Asked Questions
What counts as return fraud in fashion ecommerce?
Return fraud covers wardrobing, returning a different or counterfeit item, empty-box returns, receipt manipulation, and refund claims on orders that were delivered. Ordering multiple sizes with the intent to return the extras is not fraud, even though it inflates the same return-rate metric.
Is bracketing return fraud?
No. Bracketing is a customer compensating for a size chart they cannot trust, and it disappears when the shopper is given a size recommendation they believe. Treating it as abuse tends to push buyers to competitors rather than reduce returns.
Do paid returns reduce return fraud?
Return fees reduce total return volume, and they do deter wardrobing, which is price sensitive. They do not distinguish between abuse and genuine fit uncertainty, so the cost falls mainly on honest shoppers and shows up later as lower add-to-cart and repeat purchase rates. Details on the wider return-reduction toolkit are in How to Reduce Fashion E-Commerce Return Rates in 2026.
Conclusion
Return fraud in fashion ecommerce deserves a response, but it is a tail problem sitting behind a much larger uncertainty problem. Fix the 90% first by answering fit and colour before the order is placed, then act on the small group that is left with far better evidence.
