Under Armour Girl's Size Chart
|GIRL'S||US SIZES||CHEST (in)||WAIST (in)||HIP (in)|
CHEST: Place the 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 where your hips start. 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.Measurements updated Jul2018. For additional sizing information, please go to https://www.underarmour.com/en-us/t/size-guide.html
