Western Costume Company is a Hollywood Institution. This massive costume shop dates back to 1912 and they've dressed actors for some of the biggest hits to flash across the silver screen. More recently, they've provided costumes for television shows like Boardwalk Empire and Mad Men. While this is an industry shop, you don't have to be making a movie or TV show to get a costume here. Rentals are available by appointment, and during October they have a Halloween store where rentals are available from $45 to $325. Check their website for hours.

NOTE: WCC announced that there won't be a Halloween store this year. All Halloween rentals will be according to the WCC Private Rental Policy.
