Size Guides and Exchange Policies: Cutting Fashion Returns (2026)

E-commerce

The verdict in three sentences

In online fashion, the product return is your number-one loss item: 20 to 35 % of pieces come back, and 60 to 70 % of those returns are caused by the wrong size. A precise measurements guide (not a plain S/M/L grid) cuts returns by 8 to 14 points, while an exchange-over-refund policy keeps 55 % of the revenue that would otherwise walk out. Each return costs 2,000 to 4,500 FCFA in re-delivery and repackaging: the battle is won before the purchase, not after.

Anatomy of a fashion return and its real cost

A return is never free. You pay the return run, inspect the item, iron it, repackage it, restock it, and sometimes discount it if damaged. On a garment sold at 18,000 FCFA with a 40 % margin (7,200 FCFA), a 3,500 FCFA return eats more than half the profit. And if the customer wants a refund instead of an exchange, the sale is purely lost.

Three levels of size guide

Not all size charts are equal. The gap between "no guide" and "fit recommendation" translates directly into return points.

Simple S/M/L gridLow-2 to -4 ptsAccessories, basics
Measurements table (cm)Medium-6 to -10 ptsFitted garments
Fit recommendation by body typeHigh-10 to -14 ptsPremium, made-to-measure

The measurements table in centimeters (bust, waist, hips, length) is the best effort-to-result ratio. Add one line per product: "Awa measures 88-70-96 and wears M", and the doubt evaporates.

The exchange policy that saves revenue

When a return is unavoidable, steer toward exchange or store credit rather than a cash refund. Offer free re-delivery for an exchange, keep a fee for a refund. Result: 55 % of customers who were about to leave keep their money in your store, and you turn a loss into a fresh sale.

Mini case study

Bintou runs a women's ready-to-wear store in Abidjan: 180 orders/month, average basket 20,000 FCFA, 40 % margin. Her return rate is 30 % = 54 returns, of which 65 % are size-related (35 returns). Unit cost 3,500 FCFA = 189,000 FCFA/month in return costs.

She publishes a precise measurements table with fit recommendations. Size returns fall by 12 points: the overall rate drops from 30 % to 18 %, i.e. 32 returns instead of 54. Saving: 22 returns × 3,500 = 77,000 FCFA/month. By steering half the remaining returns to exchange, she saves another 55 % of their value, roughly 176,000 FCFA of revenue preserved over the year.

FAQ

Is a measurements table really enough?

Yes, it is the most profitable lever: it targets the 60-70 % of returns caused by size and cuts them 6 to 10 points on its own. Adding a body-type recommendation pushes the drop to 14 points on fitted items.

Should I ban refunds?

No, but steer toward exchange or credit by making it more attractive (free re-delivery, a 5 % bonus). This simple asymmetry keeps about 55 % of the revenue that would have gone out as a cash refund.

What does a return really cost?

Between 2,000 and 4,500 FCFA depending on distance and item condition: return run, repackaging, ironing, restocking. On a 7,000 FCFA margin, a single return swallows more than half the profit.

How do I measure the guide's effect?

Track the return rate by reason before and after publishing. An 8 to 14-point drop on the "size" reason within 60 days confirms the guide works; otherwise refine the measurements and add worn photos.

Does product video help too?

Yes, it cuts "color/fabric" returns by 3 to 5 points by showing the real drape and texture. Paired with the measurements table, it attacks the two main return causes at once.
