A little sizing tip!
For suits in our Foreverever fabric - if you are in between sizes, or really close to another size, we recommend you size up. For example, if you usually wear a small or medium, you will most likely be a medium in Foreverever fabric products.

For Recycled Sea-Flex fabric products, we recommend you stick to your usual size.



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.
