I bought this for my child, but the stretchy fabric wasn't to their liking, so it's only been tried on. It's a men's M size, but I recommend it for someone who usually wears a men's S size if your child likes to wear things oversized. Or, it would also be good for a tall, slender boy or someone who wears a regular M size for running. #Descente #Black #Stretch #T #Shirt
