SizeLock

SizeLock is a mobile + web AI sizing assistant for men’s clothing that reduces returns by predicting the best size per brand and item type. Users take two quick inputs: a few body measurements (manual or guided camera capture) and their best-fitting items from brands they already own. The app builds a personal fit profile (e.g., “athletic shoulders, shorter torso, prefers slim but not tight”) and maps it to brand-specific sizing quirks using a continuously updated database. When shopping, users paste a product link or search within the app to get a clear recommendation (e.g., “Medium Tall in Brand X, avoid Slim fit”). It also flags high-risk purchases (“runs small in chest”) and suggests alternative cuts. This is not magic: it works best for common categories (tees, shirts, chinos, jackets) and will be less reliable for fashion-forward cuts and inconsistent fast-fashion lines.
