ZUEVIMen's Stringer Tank Tops Muscule Cut Bodybuilding Gym Vest Y-Back Workout Sleeveless T-Shirt

I'm 5ft 1.5 122lbs. Would a small be too small or should I get medium?

does it show nipples or not or have they changed the shirt, ordered a med and while it was too long which may have made a difference....?

What % cotton is the white stringer?

Do you not carry XXL anymore?
