We build trustworthy bra fitting tools backed by data, specialist insight, and thousands of real-user measurements so you can feel confident every time you shop.
We synthesize research from lingerie brands, fit specialists, and wearer feedback to refine our sizing recommendations.
We never store entered measurements or personal data. All calculations happen client-side for complete user control.
Our database covers 28+ global sizing systems and expands as we collect feedback from diverse body profiles.
Our calculator follows international best practices: band measurements are normalized, cup volumes adjust per band size, and we offer sister-size guidance for different manufacturers.
We maintain conversion matrices for US, UK, EU, AU/NZ, Asia-Pacific, and Latin America, and cross-check with brand-specific charts from partners and publicly available references.
New logic is validated with synthetic datasets and user interviews. We monitor anonymized analytics to improve usability, clarity, and accessibility.
Accurate fits should be accessible to everyone. We work with fit educators, lingerie technologists, and health professionals to keep our advice current.
