Measurements describe Under Armour's standard, but slight variation may occur.

TAPE SIZE: Stand up wearing an unlined bra and measure tightly around the chest just under the arms, just above the bust. If your result is to one decimal place, round to the nearest whole number in the sizes listed in the table above.

BUST SIZE: Wearing an unlined bra, measure loosely around the fullest part of your bust. Same here, round to the nearest whole number in the sizes listed in the table above.

CUP SIZE: Wearing a non-padded bra, hold the measuring tape parallel and measure at the fullest part of your bust. Always round this measurement UP to the nearest whole number.

Then subtract the band size you got from the bust size to find your specific cup size.
