Under Armour size guide
How to Measure - Women's Tops
CHEST SIZE: with a tape measure, measure the chest size under the arms, around the strongest part. The point where the fingers meet indicates the measurement.
WAIST SIZE: take your natural waist size. Don't take this measurement too snugly for a bit of ease.
