y'know, Malabar DOES sell wigs, silly. ^^;; generally they're one of the 3 main places to find costume wigs if you're in downtown TO, i'd say. (malabar does costume, dance, and rental stuff)
and don't worry about planning too hard; Malabar, Curry's and the Fabric District are all on/near the SAME stretch of street :P they can all be reached in between 5 to 20 minutes if you get off at Osgoode subway station and walk west on Queen Street W.
price just varies depending on the wig and selection. but yeah, dani's store probably has slightly more selection, easily more options than what they have in-store at malabar, but i've gotten a few nice wigs at malabar before. (
this red one and
this blonde one
