Totally agree with Dena here. It's difficult to know what wig will look good on you until you try it out. And you can only do that at a local wig shop.
The employees there can give you recommendations on which wigs will suit your face shape. And then you can try on all sorts of wigs until you find the one you like. They can assist you with trimming the bangs on the wig too, if that's what you need.
