Why it is here
On cost to the shopper, ASOS charges £3.95 only if a shopper's returns top 70% of the value of their past orders, counted over 12 months. Everyone below that line keeps free returns. That is stricter than a fee on every return. — Which?
On AI models, ASOS launched a try-on tool for 10,000 products in February 2026. Shoppers can upload their own photo or pick an AI-generated model with their likeness. Each try-on loads in four to seven seconds. — Retail Week

Keep in mind
ASOS closed some accounts in 2025 for breaking its Fair Use policy. It says this is how it keeps free returns going for most shoppers. Heavy returners may be affected.
