The tag is faded and the material is unknown. It's a smooth fabric, like cotton, and dries easily. It has a light pink color with a white checkered pattern. It has lace around the edges, which is cute. I thought it was a single size, but when I put it on a mattress, it was too tight in both directions, so I think it's a semi-single size. The actual measurements are as follows. The curved parts with elastic are measured as straight lines. Length: 125 Width: 80 Depth: 24.5
