All are size Small. *NOTE: since posted I realized there is a small gray stain on the back of the white shirt, looks like a grease stain from the dumbbells at my gym. Will throw in for free. Lot of 4 women’s Nike for fit tee’s. Very gently worn. No stains on the red, blue or grey shirt. Tiny grey mark on the back of the white one, pictured below. No signs of pilling. Message me for any more pictures please!
