Review (4/5): Not as purple as the picture
This wig is more black than purple in real life, but I think it looks better that way. It seems to be a nice, high quality costume wig able to fit various head sizes. The tall braid standing up is thick and plump, not likely to deflate or fall over on its own, but it does make the wig a little unbalanced. A real person will be able to compensate easily, but my little foam head here was struggling.
This set came with a wig cap, earrings (one had a defect on the "gem"), a necklace that was lightweight, a spider clip for the hair, and two braid clips. I wasn't really sure what to do with the braid clips or how to clip them into the hair, as there didn't seem to be any flexibility in the prongs to get hair between them, but some searching revealed that they probably should be twisted up around the braid. I did that, as pictured, and you can see how I was able to hide the way the main braid was held in place with a rubber band at the end.
All in all, this was a fun little set that I think a fan of the movie Hocus Pocus will get a laugh at. It might not be the most faithful recreation, but if you don't have the time or skills to make this hairstyle for yourself, it will suit a cosplay nicely.
