NWT Christine Alexander Embellished Top Black SZ S

New Christine Alexander Top with Chrome and Rhinestone Embellishments in Black. Purchase new and never wore. Top has 6.5" Ribbed Cuffs that can be turned back, Batwing Sleeves, 5" Ribbed bottom hem and 12" wide Boat Neck. Tag says small but I feel it is an oversized small so could probably fit a medium, but please check measurements. Measurement at ribbed waist is 15.5 unstretched - stretches comfortably to 18" Sleeve from neck to cuff Approx. 30" Hard to measure armpit across because of batwings but my closest guess is 25" 88% Cotton 10% Nylon 2% Spandex
