Size & Fit Guide

How to measure

CHEST: Place tape measure under your arms at the fullest part of your chest, wrap around your body until your fingers meet and mark the measurement.

WAIST: Measure around your natural waistline-right above your hips. Be careful not to squeeze too tight to allow a little give.

HIPS: With your feet together, measure around the fullest part of your hips to ensure you’ll have enough room to move comfortably.

I got this shirt to match my Easter dress, and it matched perfectly! I love that it can be dressed up but also dressed casually. My son loves the material. It is thin but not see through! Very breathable!
