My son needed to be Chong (Cheech & Chong) for his school concert (he's 12). This worked quite well with a bandana on top. It fit him quite well, I did have to trim the mustache a bit, because it was in his mouth while singing. Of courses like any beard/mustache he got a bit sweaty, but it worked perfect for the price! He was quite a hit!
It did frizz the more you played with it, so it shouldn't be used as a toy unless you're going for frizzy.
