A bra that fits correctly will:

Lift your bust
Improve your posture
Give structure to your outfit
Make clothes look more flattering

When measuring to determine your bra size you should, if possible, wear a comfortable standard underwired bra (not padded or push-up, etc.) Also, your breasts shouldn’t be sagging; if your nipple isn’t located approximately halfway down the top half of your back, adjust your bra straps to make them tighter. You should remain in a standing position, keep your back and shoulders comfortably straight (don't hold your breath or push your chest out). Be relaxed. It can be difficult to measure yourself so you may have to ask a friend to help you, this will enable you stand in the perfect position for measuring and allow you keep your arms down by your sides.

You need two important measurements:

Band size (left), and

Cup size (right)

HOW TO MEASURE:

1. MEASURING YOUR BAND SIZE

There are 2 ways you can measure your band size. The best bet is to do it both ways to see if you get a consistent measurement.

1.) Bring the measuring tape around your back to the front, keeping it under the arms and bringing it up across to the middle of your chest (right above your bust). If you get an odd number, round up to the next even number to get your band size.

for guidance.

2.) Measure across the bottom of your band, directly under the bust and across your ribcage. Make sure to keep your measuring tape straight around the back to front. Again, if you get an odd number, round up to the next even number to get your band size.

If there is a high variance between the two figures, go with the measurement from 2 above.

2. MEASURING YOUR BUST SIZE

Cups are trickier to measure becasue the size of your breasts can actually change depending on lots of factors, like what day of the month it is and if you are experiencing bloating or not. Try to pick a day to measure your cups size when you feel (relatively) true-to-size.

a.) Measure loosely around the fullest part of your bust (which typically is where your nipples are), making sure the tape is straight and flat across the back and level with the fullest part of the bust.

3. MEASURING YOUR CUP SIZE

The bust size is the literal number you have just read on the tape measure. The cup size, however, is the difference between your band size and your bust size. Here’s a chart of standard size differences and how they equate to cup sizes.

If your bust size is less than 1 inch bigger than your band size, you’re a cup size AA.
1-inch difference = A
2-inch difference = B
3-inch difference = C
4-inch difference = D
5-inch difference = DD

Here’s an example from start to finish. Let’s say you got the measurement of 33 inches as your band size. Because it’s an odd number, you should round up to 34. When you measure around your full bust, you get 36 inches. That means there’s a two-inch difference between your full bust size and your band size. The chart above says a two-inch difference is equivalent to a “B” cup size, so your final bra size is: 34B.

One final detail. Since all bra sizes differ by region. Here is a conversion chart to help you find your bra size equivalent.
