FitSwim

FitSwim is a mobile + web AI-assisted swimsuit sizing and fit advisor that reduces returns for brands and frustration for shoppers. Shoppers answer a short fit quiz (body measurements optional), select common fit issues (gaping, digging, sliding, long torso, bust support), and the app recommends the best size and specific styles within a brand’s catalog. It also explains “why” (e.g., higher-coverage cups, adjustable straps, long-torso cuts) and suggests alterations or sister sizes when inventory is limited. For merchants, FitSwim plugs into Shopify to learn from returns/exchanges and post-purchase feedback, improving recommendations over time. Brutal truth: you won’t win by doing generic “virtual try-on” alone—people don’t trust it and it’s expensive. You win by being accurate, fast, and measurable on return-rate reduction.
