Fabletics Hot Pink Racerback Tank

Brand-new, I ordered this for my daughter and it's too big. However, this Size S runs a little small. For reference, she is 5'3" and 127 lbs. It DOES fit, but it's a snug fit. The color is bright, and there are breath vents along top. Never been worn. Sits at hip. Armpit to Armpit is 14" and shoulder to waist is 23".
