FAQ

Can I use my clothing size to find my bra size?

No. Clothing sizes such as small, medium, or large do not accurately determine bra size. Bras require specific band and cup measurements for the correct fit.

The band provides most of the support in a bra. A properly fitted band should sit comfortably around the body without riding up or feeling too tight.

Not always. Many sports bras use general sizes like XS, S, M, and L, while traditional bras use band and cup sizing. Always check the specific product size guide.

It is recommended to recheck your bra size when your body measurements change or when purchasing from a new brand, as sizing standards can vary.

The band size refers to the measurement around your rib cage beneath the bust, while the cup size represents the difference between your bust measurement and band measurement.
