Rain Forest Cafe Ladies Long Sleeve T-Shirt Gray Navy XL

Rain Forest Cafe Ladies XL Long Sleeve T-Shirt Gray & Navy. I believe it’s cotton but the tag is faded. Wash like you would a regular T-shirt. Very tiny instructions are on the tag. In the last pic there is a slight discoloration. I’m unsure if is is from the fabric dying process or if it is something else, but wanted to point it out.
