1. First, prepare a tape measure to measure the upper bust, place the tape at the highest point of the breast, and circle the body. The resulting size is the bust or upper bust. To measure the lower bust, put the tape under the breast and surround the body. The size obtained is the lower bust size.
2. Determine the basic size of the bra. Generally, the lower bust is the basic size of the bra. For example, when buying a bra, 75 in the 75a sign on the label refers to the lower bust, and the lower bust can be marked as 70, 75, 80, 85, 90 cm, etc. Determine the cup model. The cup type is determined by the depth of the breast. Generally, the English letters are used to indicate ABCDEF, etc. One cup model will be added for every 2.5cm increase in the upper and lower chest circumference.
