Our Sizing

Our Bratops are true to size with generous stretch and contouring quality fitting bra sizes from 8F to 18B. 

Typically your usual top size will be your BAMBOOB size too.

To find your perfect fit, please use these guides below. We understand how important getting the right fit is especially when buying from an online brand so we have intentionally made our sizing very straight forward. Should you have any specific questions, please reach out to us as we'd love to help you find your perfect fit. We are available at hello@bamboob.co or simply DM us on our socials.


Choose your usual top size and check if you’re within the measurements.
