Women's PolarMax Technical Base Layer Acclimate Dry V Neck Tee Made in USA

Purchased this final sale a few years ago without trying on. Tag states size S but it runs small (closer to XXS-XS, in my opinion), may possibly be junior's sizing even though the hangtag states women's? Please refer to measurements below. Material is very lightweight. Total length from base of neck to bottom hem measures approx 24". Armpit to armpit measures approx 14.5"
