100% Rayon, made in Russia. XL mens, it doesn't say slim, but it's better fitting someone under 200lbs, its stretchy though too so could wear it, it's not uncomfortably snug but i prefer something a little looser (plus put on weight lol) I'm 215lb if that gives any reference. Really quality shirt, lightweight and colorful. You cant tumble dry and needs cool iron treatment. It's fairly wrinkled but with some cool ironing it will be good to go. Fantastic summer shirt! Thanks for looking! 🌺⛵️🌴🌴🌊🏖⛱️
