The band size, the measurement tight around your rib cage just under your breasts, is written as a number. The cup size represents the volume of your generous bosom. This is written as a letter. Cup size is relative to band size (see photo 2)
The problem is that there is no global standard among bra manufacturers. You may wear a 34D in one brand and a 32FF in another. Different countries use different sizing systems. And even styles from the same lines are cut differently, giving a different fit for each individual bra. Not to mention that each one of us is shaped differently --and at different times in our lives.
So, again, being properly fitted is the key to wearing the perfect bra that will make you look and feel gorgeous. Choosing the right bra size and style for you can totally transform your figure. It can put curves back in all the right places, while giving you more comfort and confidence than ever.
