Wigs & Hair
CosCraft
Description: One of the best wig sources I've found to date. Reasonably priced, HUGE variety. Occasionally out of stock on the more popular styles, but restock quickly. Also sells wefts in almost any color you could want and a small stock of wig accessories.
CosplayMagic
Description: Specialize in character wigs, but great quality and best styling I've found yet.
Pukka Store (Iklin)
Description: Small selection of wigs, but seem to be decent quality. Reasonable prices too.
The Five Wits
Description: Not the cheapest but pretty good quality, and many character specific styles are available. They also sells wefts and other wig accessories
