SIZE CHARTS
Designer's Notes on Sizing
Our styles are designed to adapt, so they fit and flatter all body shapes. We include adjustable straps everywhere we can so you feel held in all the right places. If in doubt, size up and tighten your straps.
We recommend that customers with fuller busts size up and adjust under bust bands down.

How to Measure:
The easiest way to find your size is simply by measuring, get started by putting on your best fitting non-padded bra.
Stand up straight and measure loosely around the fullest part of your bust keeping the tape parallel across your back.
Just underneath your boobs, measure snugly around your ribcage, keeping the tape parallel across your back.
At the smallest point of your waist measure loosely keeping the tape parallel across your back.
At the Fullest part of your hip and butt, measure loosely keeping the tape parallel around the front of your body.
