Measurement Guide

Torso

The most important for finding your accurate one piece size

Measure from the top of your shoulder over the fullest part of your bust, through your legs and around, up your back to the starting point.

If you are in between torse measurements or know your torso runs long, we recommend sizing up!

Bust

Measure around the fullest part at the bust.

Waist

Measure around the smallest part of the waist.

Hips

Keep measuring tape parallel to the floor and measure around the fullest part of the hip.
