Under Armour size guide
How to measure - Women's bras
Not sure of your bra size? Our sizing tutorial will help you find the right one for you.
UNDER THE ARMS: Standing up straight and wearing an unpadded bra, measure the circumference just under the arms and above the breasts. If you get a fraction, round up to the nearest whole number (for example, round 85.5 cm to the nearest whole number, which is 86 cm).
BREAST SIZE: when wearing a bra with unpadded cups, loosely measure your bust size at the strongest point. Round to the nearest whole number (e.g. round 34.5" to 35").
cup size: Subtract your underarm measurement from your bust measurement to find your cup size. (2.5 cm difference = Cup A, 5 cm -= Cup B, 7.5 cm = Cup C, 10 cm = Cup D, 12.5 cm = Cup DD).
