I got this for a Halloween costume and only needed to wear it once; it was so cheap and flimsy it barely even worked for that. The top is very uneven and bumpy, and does not fit correctly. The rim does not fold up as shown, and it's very hard to get it to fold correctly (it comes folded down and looks totally different from the picture). I used water and a hot iron just to get it smooth enough to wear, and it still looked bad. I think it is entirely polyester or some very stiff, artificial and itchy feeling material. I would not recommend it.
