This shirt has never been worn, and it's pretty old. It's marked size 15, and L3220, if that means anything to you. It is guaranteed not to rip. I really think it's a boy's size. I think it's cotton, but it's not marked. It does say "Sweat Proof Cigarette Pocket" on the tag, so it's old. Please see shipping calculator for actual postage cost for US sales. I guarantee you that if you are overcharged by $2 or more for shipping, I will refund that amou...nt to you. Always happy to combine shipping. Thanks for looking, and good luck!
