The Problem

52% of online apparel returns are size-related. Each size return costs $10–$25 to process. Size guides are static and unhelpful — they work for the average body, not real bodies. International shoppers face confusing size conversions. Sizing uncertainty reduces conversion by 15–25% as shoppers abandon rather than guess.

The Solution

AI size recommendation widget that integrates into product pages, asks shoppers 3–4 simple questions, and recommends the perfect size based on body measurements, past purchases, and brand-specific fit data — reducing returns and increasing conversion.

Target Audience

Fashion and apparel e-commerce brands with return rates above 25%, footwear retailers losing sales due to sizing uncertainty, and brands expanding internationally where sizing standards differ

Why Now?

Fashion e-commerce continues growing but returns remain the #1 challenge. AI can now model body shapes from minimal input. Privacy-friendly approaches avoid body scanning concerns. Brands need to reduce returns for sustainability and margin goals.
