Step 1

Let's Measure Your Underband

Wrap the measuring tape around your ribcage, directly under your bust, as tightly as you'd like your bra to fit.

Step 2

Now Your Leaning Bust Measurement

Lean forward about 45 degrees and loosely wrap the measuring tape around the fullest part of your bust. For most accurate results, measure without a bra.

Fit Preference

With relaxed fit, expect less lift and a more forgiving band. Best for people who don't want to alter the natural shape of their breasts, and prioritize ribcage comfort.

With firm fit, expect more support and a tighter band. Best for people looking for major lift and don't mind a tighter band around the ribcage.
