Did you know that 80% of women do not wear the right bra? For aesthetics and comfort it is necessary to know which is the correct size to enhance and stylize the bust, improving posture. In Ras Corsetería we help you to calculate it: 1: measure the contour of the lower chest, without pressing the tape measure, to know what is your bra size (B). For example, if your outline measures 84 cm, your bra size will be 100. 2: measure the contour of the chest, at the height of the nipple (A). 3: Subtract the measurement from the contour of the chest to the lower chest. The difference will give you the result of the size of the Cup. For example, if your breast contour is 100 cm and the contour measurement of the lower chest is 84 cm, the difference will be 16 cm = Cup B.
