SizeSignal

SizeSignal is a mobile + web app that predicts how a specific garment will fit on plus-size and inclusive bodies using real-world purchase outcomes, not brand size charts. Users enter a few body measurements (or import from a past order), select fit preference (snug/true/relaxed), and the app outputs a recommended size with a confidence score plus “watch-outs” (tight in bust, short rise, narrow calf, etc.). The key is crowdsourced fit feedback tied to verified orders and returns: users can connect email receipts or retailer accounts to confirm what they bought and whether they kept it. Over time, SizeSignal builds brand-and-item-level fit profiles, highlighting which brands run small/large and which cuts work for specific body shapes. Monetization is affiliate revenue + a premium tier for wardrobe tracking and advanced fit analytics. This is not magic: it works best for popular items and improves as data grows.
