In order to find the right size bra, you will need to take your measurements. It only takes a few minutes, so let's get started.
1: Band size
Pull the tape measure around your chest, just below your underarms. Hold the tape measure so it is firm against your body, but not squeezing you. This measurement is your band size. If you get an odd number, round up.
2: Bust measurement
Now measure loosely around the fullest part of your bustline.
3: Cup size
Subtract your band size from your bust measurement to find your cup size. Match the number to this bra size chart to determine your cup size.
Let's say your bust measurement is 51 inches and your band size is 46 inches. 51-46=5, so using the chart below, you are a DD cup. You will want to shop for size 46DD bras.
|1"= A||5"= DD||9"= I|
|2"= B||6"= DDD & F||10"= J|
|3"= C||7"= G||11"= K|
|4"= D||8"= H|
One more thing:
If you haven't measured yourself for a year or more, your bra size may have changed. Exercise, aging, pregnancy, and weight gain or loss can affect your bra size. Pick a month and try to remember to measure during that month every year.

Bra fit checklist
Now that you know your right bra size, let's double-check that your bras are fitting you correctly.
The band is the main support feature of your bra, so it is important that it fits well. When you buy a new bra, fit it to the loosest row of hooks, so you can tighten it as the elastic loosens over time and washings.
Is the band secure but not too tight? If you can't fit a finger between the bra band and your body, the bra is too tight.
Is the band too loose? If there are gaps at the bottom of the cup, the band is too loose and the bra will ride up.
Does the center gore (the area between the cups) lie flat?
Can you stick a finger under the center gore? The center gore should be tighter than that to keep your breasts from slipping out the bottom.
Are there "empty spots" in the cups of your bra? The cups should look full and smooth. If there are pockets in the fit, you need a smaller cup size.
Is there spillage on the sides (under your arms) or over the top of the cups? If so, you need a larger cup size or a bra design with more cup coverage and/or higher sides.
If you wear an underwire bra, is the underwire flat against your chest? If the underwire is riding up, you need a larger cup size. If it is pinching or poking, you need to buy a new bra.
Look for adjustable straps so you can tighten the strap over time as the elastic loosens.
Do the straps rest comfortably on your shoulders without pinching or digging? You don't want to see a reddish strap imprint when you take your bra off at the end of the day. Adjust the straps, switch to convertible straps, or try a different band size.
Do the straps slip off your shoulders? If adjusting the straps doesn't fix the problem, toss the bra. Either the elastic has lost it or you need a different size.
