I thought it would be fine since it's size S, so I bought it for my child, but the neckline was a little too big for my elementary school child, so they gave up on wearing it. ^_^ It's only been tried on, and I've washed it once since it was tried on. It's 100% cotton and has a smooth, light fabric. I think it's easy to use both on and off, and it's a design that's easy to match. The color is black.
