Bra sizing varies significantly between countries. Band sizes indicate the circumference under the bust, while cup sizes indicate the difference between bust and underbust.
How Sizing Works
Japan uses band sizes in centimeters (65, 70, 75...) with letter cup sizes. US/UK use inch-based band sizes with letter cups. EU uses different numbering.
Getting the Right Fit
For the best fit, professional fitting is recommended. Size can vary between brands and styles. Always try on when possible.
