Returns automation cutting 40%+ bra RMA, what does size-exchange-first look like?

Lingerie return rates are the highest of any apparel category, brands routinely see 40-55% for bras (vs 25-30% for general apparel). Most of those returns are size-related, not style-related.

Size-exchange-first flow:

• Customer initiates RMA through Loop Returns / Returnly / Aftership Returns (any of the three integrate cleanly with Magento).
• First screen: reason picker. If “wrong size” or “doesn’t fit,” system pulls the customer’s saved fit-quiz data + their primary + sister sizes from Magento customer attributes.
• Second screen: size suggestion. “You bought 34D. If the cup was small, try 34DD or 32DDD (sister size). If the band was tight, try 36D. If both, try 36DD.” Shows live stock badges per suggestion.
• Customer picks the new size → free exchange shipping + the original is RMA’d on return.
• Fallback: store credit + 10% bonus if exchange isn’t the answer. Last resort: cash refund. The order of options matters, in the data I see, 45-60% of bra returns convert to exchange when offered first.

Hygiene rules:

• Shapewear, thong underwear, swimwear are final sale with a hygiene-seal photo-proof requirement on RMA submission (proves seal is intact = unused).
• Bras + sleepwear + sports bras are returnable within 30 days with tags attached.
• Serial-returner blacklist by email + shipping fingerprint after >4 returns / 6 months. Doesn’t block the customer, just routes them to manual review and disables free shipping.

Net effect: cash-refund leakage drops 50-70%, RMA processing time drops 70%, and customer-reported satisfaction goes up because the size suggestion is the answer they wanted anyway.
