Size Guide
Our T0-T5 sizing is built from scratch for the 8-12 body. Not scaled-down adult. Not stretched-up kids'.
How to Measure
Measure in underwear or a lightweight tee for the most accurate results.
Chest
Wrap the measuring tape around the fullest part of the chest, under the arms. Keep the tape level and snug but not tight.
Waist
Measure around the narrowest part of the waist, usually just above the belly button.
Hip
Measure around the fullest part of the hips and buttocks.
