Take matters into your own hands How to Measure Bra Size

Our how-to guide for when you just can’t get to a fitting room.

Follow these easy bra fitting steps or check the video to follow along.

  1. Measure your band. Wear a lightly lined (non-push-up) bra so your breasts are as close to natural as possible. Wrap a measuring tape directly under your breasts. Make sure it’s directly parallel with the bottom of the bra band.
  2. Now measure your bust. Place the tape at the fullest part of your bust. Make sure it’s parallel to your band again.
  3. Subtract the band size from your bust size to find the right cup size. Every inch equals one cup size up. Check our chart below.

Next, the details. Anatomy of a Bra

We started from scratch, studied individual shapes, tested and fine-tuned and totally reimagined what a bra could (and should) do. The result? All new elements, made specifically for your body.

Rigid Front Straps

Don’t let the word “rigid” fool you. You actually want straps with slightly less give. They won’t stretch out as the hours wear on – which means the girls stay lifted literally all day.

No-Slip Adjusters

Courtesy of grippers that seriously won’t move, so you can retire from the Strap Check Game. (You know, constantly checking to make sure yours aren’t at your elbows.)

U-Back Design

Those back bulges? Harsh, straight lines bring ‘em to the fore. This gentler curve mimics the shape of your body, so your bra works with you…not against you.

Padded Hook & Eye

Metal pieces digging into your back? Yeah, no good. This extra padding is such a no-brainer, we’re shocked it’s not already an industry standard.
