The verdict in three sentences
In fashion, a return is not an incident: it is a structural cost line, and in Lagos sizing is its main cause. On a 30 % return rate, 62 % of cases come from a garment that does not fit — an information problem, not a product one. Three fixes exist, from a detailed size guide to virtual fit, and they stack to protect margin and lift conversion by 7 %.
Three fixes against sizing returns
The table compares the effect of each device on the return rate (2026 order of magnitude, Lagos fashion).
| Device | Effect on return rate | Setup effort |
|---|---|---|
| None (baseline) | 30 % returns, 62 % size-related | — |
| Detailed size guide | -9 points | Low |
| Real per-item measurements | -6 points | Medium |
| Virtual fit | -12 points | High |
| Size recommendation | +7 % conversion | Medium |
A detailed guide alone removes 9 points from the return rate: the best effort/impact ratio. Real per-item measurements (not a standard chart) add 6 more points. Virtual fit, heavier to build, offers the strongest single gain at 12 points.
The economics of an avoided return
| Item | 2026 order of magnitude |
|---|---|
| Cost of a return (logistics + restocking) | 3,500 FCFA |
| Conversion gain with size recommendation | +7 % |
| Reviews mentioning fit | +5 % trust |
| Refund delay via mobile money | 48 h |
| Target return rate after devices | 12-15 % |
Each return costs roughly 3,500 FCFA in reverse logistics and restocking, not counting sometimes-damaged items. A refund within 48 h preserves the customer relationship even on a return, and reviews that mention fit reassure the next buyers (+5 %).
Mini case study
Aminata runs an online fashion store in Lagos, selling 800 items a month with 30 % returns, i.e. 240 returns. By deploying a detailed size guide (-9 points) and virtual fit (-12 points), she brings the rate to about 15 %, i.e. 120 returns. She avoids 120 returns at 3,500 FCFA = 420,000 FCFA a month. On top, size recommendation lifts conversion by 7 %, adding around fifty monthly sales. The virtual-fit investment is absorbed within a few months.

FAQ
What share of fashion returns really comes from sizing?
In Lagos in 2026, about 62 % of returns on a 30 % overall rate are size-related. It is therefore the first lever to pull before any other.
Is a size guide enough or is virtual fit needed?
A detailed guide already removes 9 points for low effort. Virtual fit adds up to 12 points but costs more: start with the guide and per-item measurements, then add virtual fit if volume justifies it.
How much does a return really cost?
About 3,500 FCFA across reverse logistics, inspection and restocking, not counting damaged items. Cutting the return rate is thus a direct margin gain, not just comfort.
Why does a fast refund matter?
A refund within 48 h preserves trust: a customer disappointed by a size stays a customer if the return is smooth. It also fuels positive reviews that mention reliable sizing.
