The cups of a bra can visually reflect the size and specific dimensions of the breasts, but many women do not quite understand the meaning and measurement of the size code. If you’re not sure, you’ll naturally understand it after reading this page. First, the cup measurement Measurement of the body position: first the clothes off, more relaxed standing (but straight), feet together, face to the front, slightly lifting the jaw. Circle the tape measure horizontally around the bust (protruding point) and tighten it slowly from loose. Gently hold your breasts up with your hands as if you were wearing a corset. At this point, you can easily measure your actual bust (one week past the fullest part of your breasts at nipple level) and your lower bust (the smallest bust value at the bottom of your breasts at the lower edge of your breasts). It is best to have someone to help you with the measurement, as self-measurement can lead to errors. The first step is to know your lower bust. Those with sagging breasts should push their breasts up to their normal position. The available sizes are: 70, 75, 80, 85, 90, 95, 100, 105, which are all multiples of five and allow for an error of plus or minus 2.5cm, for example, if you measure 77cm, it is only logical that you should wear a 75 bra. Just kidding, if it’s such a coincidence, you have to try both 75 and 80. Step 2: Determine the cup of the bra Cup is those numbers after the ABCD, bust difference refers to the number of your upper bust minus your lower bust, the allowable error is plus or minus 1.25cm. such as your bust difference is 13cm, that is of course B cup. Generally speaking, the difference between the upper and lower bra is about 7.5cm, AA cup, 10cm A cup, 12.5cm B cup, 15cm C cup, 17.5cm D cup, 20cm E cup, and 20cm F cup. Step 3: Lower bust plus cup code For example: your lower bust measurement is 70, your upper bust measurement is 85, the two numbers subtracted 15cm, that is C cup, put the two together, you should wear the bra for 70C. There are two more points need to tell the majority of women friends: usually, the size of the underbust bra are slightly adjustable through the back buckle to meet the comfort needs. Therefore, some bra sizes can be common. For example, 75A and 70B can be common, that is to say, the underbust is one size smaller, while the cup is one size larger, generally can be common. Due to the manufacturer, material, cup type and style and some other reasons, there are different cup types, such as half cup, three-quarter cup, etc., there are some personal differences, so you are advised to try on when buying bras.
