FAQs

How to find the right Band Size?

Put on a non-padded bra that fits you well to find your band size. Find a measuring tape, and stand in front of a mirror. Wrap the tape around your body just underneath your bust. The measuring tape should be horizontal to the floor, and quite snug.
The measurement in inches is your band size. If it’s an odd number, round down to the nearest even number.

How to Find the right Bust Size?

To find your bust size, measure around the fullest part of your breasts.

How to Find the right Cup Size?

To find the right cup size, take the values of your Bust size (breast size) and subtract the band measurement, e.g. if you measure 31 underneath your breasts, and 34 around, the result is 34-31 = 3. Use the result to find your cup size in the US bra size charts below.

What size bra is considered plus size?

Plus-sized bras have a band size of 38 or larger. There is one distinction in bigger sized bras.
A Full figure bra encompasses sizes DD+ with a 38 or larger band.
All full-figure bras are plus size, but not all plus size bras are full-figure:
A 38F would be considered full figure and plus size, but a 40B would be just plus size.
