I have two wigs from WigFashion, they're both different wig brands but they're amazing. One is really thin and has a small cap, but the fibers of the wig are astounding and feel AND look like real hair, plus it never tangles. The other wig isn't as soft, but the head is huge and actually fits me (I have a huge head and super thick hair) and the fibers aren't awful.
However, EpicCosplay has nicer wigs, I think. They're anti-tangle, and it's amazing to run your fingers through them.
