Size Guide

Sports Bras/ Tops

Use your underbust measurement to find your ideal 100%LIFE fit.

If you’re between sizes, sizing up offers a softer, more relaxed fit, while sizing down provides a snug, more supportive feel. Listen to your body—comfort looks different for everyone.

How to measure

Figure out your size with these guidelines and a tape measure. If you don’t have one, use a piece of string or ribbon and then measure it with a ruler. Just make sure the tape is slightly loose and parallel to the floor. Here's where to place your measuring tape:

Under bust - measure around your body right under your breasts(where the bra band sits)

Waist - This is the soft area directly above your hipbone, but below your rib cage. Start measuring from your belly button, bringing it the whole way around your body.

Hip - Measure the circumference of your hips. Starting at one hip, measure over the longest part of your buttocks, all the way around to where you started.

You can also try comparing our measurements with clothes you already own. Place your garment on a flat surface and measure with a tape or ruler. If the measurements are taken flat across the garment, double them.
