Auditing Bracketing Returns: When Fit Data, Not Fraud, Is the Problem
October 17, 2026
Bracketing is the practice of ordering two or three sizes of the same item and returning the ones that do not fit. It inflates return rates, ties up inventory, and can cost more than wardrobing in some categories, but it is not fraud: the customer keeps and pays for an item. Auditing bracketing means measuring how much of it your own size information causes, through inconsistent sizing, missing measurements, and reviews you never mined, and fixing those causes instead of punishing the behavior.
Measure bracketing separately or not at all
Start by isolating true brackets: the same customer, the same style, two or more sizes, one kept, in one order or a tight window of orders. Most return dashboards bury brackets inside the general return rate, which makes fit problems look like fraud problems and sends the loss prevention team chasing your most honest customers.
Report the bracket rate by category and by style, not chainwide. A chainwide average hides the story: one badly sized shoe line can produce most of a networks bracketing, while the rest of the catalog fits the way customers expect. The audit unit is the individual style, because that is where the fix will happen.
Interrogate your own size information
For each high bracket style, audit what the customer was told: Is there a size chart, and is it this brands chart or a generic one? Are garment measurements given, or only body measurements? Do reviews mention runs small or runs large, and has anyone read them this season? Missing or wrong information at this level manufactures brackets at scale.
Then check consistency across your own range. If your size medium dress measures like a competitors small, returning customers will bracket even when first time customers do not, because their learned size betrays them. A simple audit of actual garment measurements across the top returned styles finds these traps within a week.
Tell bracketing from wardrobing in the data
The two patterns share a high return rate and nothing else. Bracketers keep an item from almost every order, return unworn extras quickly, and their returns show no wear on inspection. Wardrobers keep nothing from event category orders and return items with wear signs after event dates. Mixing them in one metric produces policies that annoy the first group and miss the second.
Use the kept item as the pivot in your reporting: accounts and orders with a kept item are a fit story until proven otherwise. That single distinction should route bracketing to the ecommerce and product teams, where it belongs, and keep it out of fraud queues entirely.
Fixes that actually reduce brackets
Publish garment measurements for high bracket styles, add fit notes written from returns data, and surface review based guidance like eighty percent of buyers say this runs small at the moment of size selection. Each fix is cheap; together they routinely cut bracketing in a problem category by a third or more within a season.
Reserve policy friction for the extreme tail: accounts bracketing nearly every order with nothing kept are not bracketing at all, and the data review will show it. Everyone else is telling you your sizes are hard to predict. An audit that ends in better size information pays for itself; one that ends in customer penalties just exports the sale to a competitor with a clearer chart.

Frequently asked questions
Is bracketing a form of return fraud?
No. Bracketing is a rational response to uncertain sizing: the customer pays for and keeps an item. It becomes a problem worth managing because of shipping, handling, and inventory costs, not because of dishonesty. Treating bracketers like fraudsters is both unfair and ineffective, since the cause is usually the retailers own size information.
How can we tell how much bracketing a style causes?
Look at the share of multi size orders for that style and the direction of the keep: if customers systematically keep the size up, the style runs small and the chart or the cut is lying. Random keeps in both directions suggest normal fit uncertainty. Systematic keeps are a measurement confession.
Should retailers charge for return shipping to stop bracketing?
It reduces bracketing, but bluntly: it also reduces first orders from new customers who cannot predict your sizing. Targeted versions work better, like free exchanges for a different size, which attacks the fit problem directly and keeps the kept item rate high.
What is a healthy bracketing rate?
It varies by category: footwear and tailored clothing naturally bracket more than basics. The useful comparison is your rate per style against its own history and against similar styles in your range. A style bracketing at twice the rate of its neighbors is the audit finding, whatever the absolute number.
