Sizing Chart

We make sizing easy for tweens and teens with a clear, thoughtfully designed size chart. For best results, measure around the fullest part of the chest and the natural waistline — these two measurements are key to achieving the perfect fit.

Where to measure

Bust

Measure under your arms at the fuller part of your bust. Keep tape level across your shoulder blades.

Natural Waist

Measure around your natural waistline, keeping the tape comfortably loose.

Hips

Stand with your feet together and measure around the fullest part of your hips.

Note

Fabrics can fit and feel differently depending on the material. Structured fabrics offer little to no stretch, while softer styles provide a more flexible and comfortable fit.
