Our bras run true to size. Follow the instructions here to work out your size using a tape measure. Please note that this is not always perfectly accurate for everyone. Additionally, compared to standard retail sizes, we recommend considering selecting a size smaller, as our real-size measurements tend to run larger. Combined with the tips below, this should ensure you find the right size for you.

Sister sizes for bras are a concept used to find a bra that fits when the cup fits well but the band does not, or vice versa. It’s based on the idea that volume is constant across different band sizes. For example, if you decrease the band size, you must go up a cup size to maintain the same cup volume. Conversely, if you increase the band size, you must go down a cup size.

To find a sister size with a smaller band, you decrease the band size by one interval (e.g., from 34 to 32) and go up one cup size (e.g., from B to C). To find a sister size with a larger band, you increase the band size by one interval (e.g., from 34 to 36) and go down one cup size (e.g., from B to A).

This system helps you find a bra that better fits your body’s shape and size, especially if you find a bra that fits perfectly in the cups but is too tight or too loose around the band. Remember, sister sizing is a starting point for finding a better fit and may require further adjustments based on the specific bra design and personal comfort.
