The best option to know the size of a bra is to match it in the store. There sales consultants will tell you, and you pricenice that size was. But if you cannot visit the lingerie store, or you want to order a bra in online store, then you need to take the measurements and on the table to determine your size.
The size of a bra is determined by two components - the underbust girth and the Cup size. It is best to ask someone to measure you, so the figures will be more accurate. Put the easiest and most convenient your bra. It should not lift or pull the breast, as well there shouldn't be any additional inserts. When taking measurements it is necessary to lower hands, to raise them is not necessary, otherwise the measurement will be incorrect. Then exhale air and relax. Take a tape measure and first measure the girth under the chest. The obtained results must be rounded like so:
measurements 68-72 73-77 78-82 83-87 88-92
size 70 75 80 85 90.
Next, you need to measure the girth of the chest. Straighten your shoulders and stand straight. Exhale, take the measuring tape and measure the chest at its widest part. When taking measurements, hold the tape horizontally, or tight chest. To determine Cup size, you must measure from the underbust girth to take the measure of the girth of the chest. The amount that a Cup can be defined by the table:
The difference in cm 12 14 16 18 20 22
Size Cup A B C D E F
So, if for example, under the chest girth 79 cm, and the girth of the chest of 95 cm the size of the obtained 80C.
However, this definition of size is rather arbitrary, and the likelihood that the bodice will suit you, is about 70 %. Size bra can vary depending on the manufacturer. If you decide to order lingerie online store, be sure to verify their data against the information in the dimension table provided on the website. If you are asked, for example, a friend to buy for you bra, give her your measurements. This will help sellers consultants to find a suitable for you bodice.
