● PRACTICAL GUIDE 2026
Returns cost European fashion e-commerce over €7 billion per year. AI can drastically reduce them — which tool should you choose?
Updated July 2026 · 6 min read
▶ SHORT ANSWER
The three most effective AI tools to reduce fashion returns: (1) AI size recommendation, which addresses the most frequent cause of returns, (2) AI virtual try-on, which tackles perceived fit, (3) a 3D product configurator, which reduces unmet expectations on colours and materials. WeWear offers all three.
The majority
Wrong size
Too big, too small, unexpected fit
A significant share
Visual expectations
Product doesn't match photos (color, texture, perceived fit)
A minority
Defects / other
Defective product, delivery delay, change of mind

AI sizing + virtual try-on. AI sizing addresses the most common cause of returns; virtual try-on tackles the share of returns driven by perceived fit. WeWear offers both, and we recommend measuring the combined impact with an A/B test.
