Anyone know where to get good Cosplay outfits?

The best cosplays are the ones that you make yourself. They have the most uniqueness/originality.
Cosplay.com is a good place to get started if you want ideas.
If you want decent site for really good wigs/accessories at a dirt cheap price try Bodyline. It's a Japanese site and takes about a month to ship but most of the site is in English and the S&H is dirt cheap considering.
