To measure your bra size, start by running a tape measure all the way around your body, just underneath your breasts, to get your band size in inches. You've found a new bra that fits well, maybe in a different size or style to the ones you're used to. Not Helpful 2 Helpful Different brands and styles may have more or less stretchy bands. It needs to be firm enough that the bra is still fairly supportive without weighing down heavily on the shoulder straps.
Subtract your band size from your bust measurement and refer to chart. So how can you tell if a particular style fits? Bend forward at the waist, then slip on the bra and hook it. This ensures your breasts are completely in the cups. The back of the bra should be level with the front. Make sure the bra is not too loose. You should be able to slide only one finger underneath the band. First, tighten the band, then shorten the straps.
Put on a close-fitting shirt over the bra. If the cups pucker or your breasts bulge, you're not wearing the correct size. Look at yourself sideways in a mirror. Your breasts should sit midway between your shoulders and elbows. If not, you need a more supportive and better-fitting bra.
If you need to go down a cup size for fit, go up one band size, and vice versa. The person who wears a 28DD, for example, has less breast tissue than the person who wears the 34DD. In fact, a 34DD is cup size equivalent to 28FF! Below are some sample measurements for a person who might wear these sizes:. As you can see, each DD cup represents not only a completely different set of measurements but also a completely different sized person. However, I do want to note that some people choose to size up in the band for comfort or health reasons.
For example, the person measuring a 28DD may actually prefer a 30 or 32 band, making the new cup size a 30D or a 32C. The Moral of the Story: Cup size cannot and should not be used as way of representing breast size. All that matters is you find the bra size that fits, flatters, and feels comfortable to you! As you grow, you will need to increase your cup size, but your band size may stay the same for many years unless you put on weight around your ribs. Cup sizes are in proportion to the band size, so an A cup on a 34 band is smaller than an A cup on a 36 band - one size smaller to be precise.
A 36A is equivalent to a 34B. You might think of a D cup as being very big, but a 32D is much smaller than a 38D. The standard measuring system that you often hear about, which requires you to add 4 or 5 inches to your under-bust measurement, does not work at all. It is not uncommon to go for a bra fitting wearing a 36B and come out in a 32DD. That's a drop of 2 band sizes and an increase of 1 cup size. This should be your band size. It's a bit more difficult to accurately calculate your cup size from your measurements.
The best way to find out is to try some bras on. For example if you are wearing a 34A at the moment, and your under-bust measurement is 30 inches, then you'll probably need a 30C. You need to go up by one cup size for every band size you go down, because the cups are sized relative to the band. If everyone wore correctly fitting bras, the average adult woman would be in a 34DD. Obviously the average for girls who are still growing will be smaller.
You will be able to tell if you have the right band size when you can only just fasten it, but it is still comfortable. If you are able to comfortably fasten it on the tightest adjustment, it's too big. The links listed below will explain in more detail how to tell if your bra fits: The letter generally A-D but goes as high as G is the bra's cup size. The bigger the actual size of your boob, the larger cup size you will need.
Bra sizes that are the same in volume are often referred to as “sister sizes”. The grey cells in the table below demonstrate how the sizes diagonally adjacent from the top right to the bottom left are the same in breast volume i.e. the same volume of breast tissue spread across different size rib cages (band sizes). When talking about bra sizes, we will be referring about bras that use letter and numbers for sizing. Usually start with a number followed a letter(that can be repeated), a few examples: 34B; 36DD; 28G; 40E; The number indicates the band size of a bra. This makes reference to your the size of your torso/ribcage right below your breasts. Traditional bra sizes are a combination of letters and numbers. The number portion of the size (the 34 in 34C for example) represents your band size or the measurement around your rib .
