Crinkle Boxy Crop T-Shirt

I ordered 3 of these because they were exactly the cut I was looking for, but I'm undecided about keeping them. From the pictures, they looked like they had the texture/sheen of linen or crepe cotton (and totally my fault--I thought I'd seen in the listing that they were linen, which is the only reason I bought them), but in person, they've got a sheen to them that I think makes them look a bit less casual and simple than what I really wanted. They're beautiful, but I definitely wouldn't have ordered them if I'd noticed the rayon in the listing.
