A loose band steals support from the entire bra, even when the cup letter appears right.

FAQ
Answers users and ad reviewers both expect to see clearly
Is this bra size calculator a replacement for an in-person fitting?
No. It is a professional starting point that works best when you confirm the result with real bra fit feedback such as band level, wire position, and cup containment.
Can I use the site for UK, EU, FR, AU, and JP sizes?
Yes. The calculator translates the starting size across major regional systems and shows sister-size options to make shopping simpler.
Does the site store my body measurements?
The calculator runs in the browser and does not send measurements to a server in this starter build. Cookie settings are available for future analytics and advertising controls.
Why does the model visualizer matter?
Many users understand volume better when they can see how cup progression and band changes affect scale. The visualizer turns abstract size changes into something easier to compare.
Will the site be ready for Google Ads?
The architecture includes policy pages, consent controls, and ad-safe layout placeholders. Before serving personalized ads in the EEA, UK, or Switzerland, you still need a Google-certified CMP in production.
