The size is 18-24M, which I think is equivalent to a 90. It's thin, so it's easy to carry around and would be useful in spring and autumn, or indoors with air conditioning in the summer. I've forgotten the original color, but since two girls have used it, I think there's some fading and stretching compared to when it was new. Also, there were some stains on the back. Since it's 100% cotton, it was safe for my daughter, who has sensitive skin.
