Apparel sizing disputes win on size-chart visibility. Cardholder claims the size was wrong. Merchant must show the size chart was visible at checkout AND matched what shipped. Merchants with prominent size charts + measurement guides win 55–70% of sizing SNADs. Merchants without visible size guides win 25–40%. Frictionless returns beat representment for most cases below $75 AOV.
The apparel chargeback pattern
DTC apparel brands concentrate chargebacks in:
- [Visa 13.3](/reason-codes/visa-13-3) / Amex C31 (defective / not as described) — including sizing complaints. Highest-volume for apparel.
- Visa 13.1 / Amex C08 (not received) — standard delivery disputes.
- Visa 10.4 / MC 4837 / Amex F29 (CNP fraud) — often friendly fraud from teenagers using parents' cards.
Sizing complaints under 13.3 are the apparel-specific pattern. Customer orders size M, receives size M, decides it doesn't fit their body the way they wanted, files 13.3 claiming "not as described."
Technically, if the merchant shipped what was ordered (correct SKU), it's not "not as described." But issuers often side with cardholders on sizing without documentation.
Evidence stack
For apparel sizing 13.3:
- Size chart visible at checkout — screenshot of the size chart on the product page, dated to purchase.
- Measurements table — chest/waist/inseam measurements matching the customer's chosen size.
- Ordered SKU matches shipped SKU — order record + fulfillment record.
- Return policy display — clear return-window and terms visible at checkout.
- System log — no return request submitted.
Cover narrative: "Cardholder [name], order #[X], ordered size M (chest 40", waist 34" per attached size chart). Fulfillment record confirms size M shipped. Return policy allows returns within 30 days; no return request was submitted (system logs attached)."
Win rate: 55–70% with size-chart evidence. 25–40% without.
Prevention: size charts + returns
Apparel prevention:
- Prominent size chart on every product page.
- Body measurements guide — how to measure yourself.
- Model measurements — what size the model in photos is wearing.
- Frictionless returns — one-click return label, no reason required.
- Fit predictor (optional) — tools like True Fit reduce returns 15–25% and cut sizing SNADs proportionally.
For sub-$75 apparel, self-service refund usually beats representment. Fee + ops cost exceeds recovery even on wins.
Frequently asked questions
Why do apparel brands get more sizing chargebacks?
Fit is subjective and sizing varies across brands. Cardholders who don't like the fit often file 13.3 (SNAD) rather than requesting a return. Documentation of the size chart is the primary defense.
Should I fight sizing chargebacks?
Below ~$75 AOV, self-service refund is usually cheaper. Above that, size-chart evidence wins 55–70%.
