Why Bra Education is Important

Bra education is important. For tween and teen girls navigating their changing bodies, we design bras that help them feel great. We're here to spread a message of self-love for teen girls, young women, and their parents. Many moms could use more fit assistance and bra knowledge, too. BRABAR bridges the gap between childhood and adulthood bras for teenage girls — age and bra size are not the same thing, and teens with fuller busts need supportive, comfortable bras designed specifically for them. The first bra is more than just a product: parents and daughters are navigating a lot at once, and we want to make that time a little easier with real information.

Where's the problem? Bra sizing comes down to understanding the basic math of bra fitting. Brands start from the same raw data when developing new products: the ribcage/underbust measurement and the fullest part of the bust, which are the same regardless of which brand you're measuring for.

The issue is the discrepancy in measuring methods between brands, especially for the wearer. Teens in particular have a real need for band sizes smaller than 32 inches. Bra sizing is a relationship between two numbers, and offering band sizes for smaller frames or larger cups is essential for an inclusive, proper fit for teenage girls who are currently overlooked by most sizing charts. Teen bodies aren't smaller versions of adult bodies — proportions can differ, and frames are often smaller, which is exactly why a one-size-fits-teens approach doesn't work.

BRABAR Bra Size Calculator - How to measure at home in under 5 minutes

You can begin by measuring the ribcage.

Measure directly underneath the bust, wrapping around the ribcage. Round the measurement to the nearest even number to determine the band size. The band size is your ribcage measurement.

Next, we'll look at measuring the bust.

Hold the measuring tape parallel to the floor while measuring around the back, starting at the fullest part of the bust. Then, round to the nearest whole number to receive your bust size.

Finally, you can measure bra cup size at home using the bust measurement you just received.

Subtract your band size from your bust size, and that's your cup size.

The cup capacity is calculated in inches:

A cup = 1 inch
B cup = 2 inches
C cup = 3 inches
D cup = 4 inches
DD/E cup = 5 inches
DDD/F = 6 inches

Here are some bra size examples for visual reference:

BAND 28 BUST 32 = 28D
BAND 30 BUST 35 = 30DD/E
BAND 32 BUST 36 = 32D
BAND 34 BUST 35 = 34A
BAND 36 BUST 39 = 36C
BAND 38 BUST 42 = 38D
BAND 28 BUST 34 = 28DDD/F
BAND 30 BUST 36 = 30DDD/F
BAND 30 BUST 32 = 30B
