I found a site that gives hilarious costumes ideas I haven't seen on other sites (and believe me, I've searched them all). There are links to buy and the prices are very decent.
Pros: All kinds of costumes in many categories, great site to visit if you're stumped on what to be for halloween this year. Prices are low, too.
Cons: Lacking the "sexy" ideas category, would have liked to see some pictures of sexy girls haha.
