How does bra sizing work?
Bra sizes are based on your band size (the number) and your bra cup size (the letter). The number/letter is your bra size. Finding the right bra size is crucial for the right support and for a smooth, comfortable fit.
How to measure your bra size?
To determine your bra size, grab a measuring tape and use these 3 simple steps for measuring your bra size:
Step 1: Take your bust measurement
Wrap a measuring tape around the fullest part of your bust and then round to the nearest whole number.
Step 2: Determine your band size
Measure around your torso directly under your bust where the band would naturally sit. Round to the nearest whole number. When that number is even, add four inches to it; if the number is odd, add five inches to it—your band size is the sum of this calculation.
Step 3: Calculate your bra cup size
To determine your cup size, subtract your band measurement from your bust measurement.For example, if your bust measurement is 38” and your band size is 34” (38” - 34” = 4”), your cup size would be a D.
See our handy cup size conversion chart below to determine your cup size:

What is a Sister Bra Size? Sister sizing refers to bra sizes that are grouped in the same family depending on their cup volume. To determine your sister bra size, you will need to go up a band size and down a cup size. So, if you can’t find a 34C, go for its sister sizes of 36B or 32D.
What are some of the common bra fit problems? Bra fit issues range from wrinkly cups to bras that hikes up. Here are some of the common bra fit issues and solutions to help you make the right selection:
The straps dig in. Use the adjusters to move your straps up or down. Your straps should not be too tight or too loose,
The bra cups are too loose. The bra cup should cover your entire bust without any gaps.
The bra cups are too tight. There should not be any spillage from the cups.
The bra band is too tight. Your bra band should fit snugly, yet still allow you to breathe in and out comfortably.
The bra band rises up. Your bra band may be too big. You will need to fasten your hooks on a tighter section.
The bra band creates bulges. This means band size is too small.
Shopping Tip. Stock up and buy more than one bra. We suggest 3: one to wear, one to wash and one for the next day. Putting your bras on rotation will help avoid deterioration of the elastic because nothing is worse than an out of shape bra! Shop Walmart for the best-fitting bras for every size and shape.
