Hello Kitty black women's tshirts

This is a medium 100% cotton women's T-shirt but fits like a small. Armpit to armpit is 16 1/2 inches. Not a lot of room for stretch. Has a little sparkle on the white tried to grab in photo. Purchased at Universal Studios in Orlando. Wore about 3 times. Pet and smoke free home. #hellokitty #hellokittytee #hellokittyfashion #hellokittywomenstee
