Find Your Bra Size

Not sure where to start? You’re in the right place. It only takes 2 minutes to find your perfect fit.

Grab a soft measuring tape and wear your best fitting, least padded bra.

Don't have a measuring tape?

Step 1: Measure your Band Size

Stand in front of the mirror and wrap the tape around your back, just below the shoulder blades and under your bust.

Make sure that the measuring tape is parallel to the floor. Pull to a snug fit. Take the measurement and input below.

Step 2: Measure your Bust Size

Slide the measuring tape up your back, across your shoulder blades and around the fullest part of your bust.

Hold the tape as loosely as possible so that you’re not indenting or pressing into the skin. Make sure that the measuring tape is parallel to the floor.

Note the number on the tape and enter it below.

Wait, what's my sister size?

Find Your Sister Size

We don't carry sister sizes for that one!

If your band is too tight try a #{upperSister}
shop by #{upperSister} >

If your band is too loose try a #{lowerSister}
shop by #{lowerSister} >

Wait, what's my sister size?

Glad you asked! It's an alternative bra size that mantains the same cup volume as your usual size just with a different sized band.

Choose your sister size if you feel good about your cup but want the band to fit tighter or looser.

PSA: Same cup volume doesn’t mean same cup letter.

For example
If you're usually a 34B, your sister sizes would be 32C and 36A.
