The bra you're wearing was designed in the 1930s.

...and 100 years later we're still using that same bra sizing system. Say hello to a modern sizing system. Developed by women, for women, in the year 2023.

Band sizing designed to fit you.

You can adjust your Wherewithal Band Size between what would traditionally be 3 separate band sizes.

Use your underbust measurement (in inches) or your traditional band size to find your Wherewithal Band Size in the chart below.

Wherewithal band size Underbust Measurements Traditional Band Size
1 26in-30in 30 / 32 / 34
2 30in-34in 34 / 36 / 38
3 34in-38in 38 / 40 / 42
4 38in-42in 42 / 44 / 46
*bra companies add 4 to your underbust measurement to find your band size

Cup Sizing, Without the Guesswork

Bra sizing is confusing because they have made it impossible to figure out on our own.

  • Bra cups are labeled A, B, C, D, DD/E, etc. but these cup labels don’t actually stand for anything because a 34C, 36B, 38A are all the same cup size.

Our cups are labeled based on size, on a smallest to largest basis. Select your cup size by using what you would classify your cup size in traditional A-B-C sizing in the chart below.

Wherewithal Cup Size Traditional Cup Size Comparison
6 AAA/AA
7 A/B
8 B/C
9 C/D
10 D/DD
11 DD/DDD
12 DDD/G
13 H/I
14 I/J
Pair your Wherewithal Band Size with your Cup Size for your Wherewithal Bra Size. (i.e. 1/8 | 2/9 | 3/11 | 4/14, etc.)
