Victorian Trading Company (above)
There are the usual places like Party City and Spirit Halloween to shop for Halloween items, but I like to get things that are unique, individual, and sometimes so damn pretty, you use them year-round if you're a horror/Victorian Era freak like me. In fact, I suspect that any of these shops you would want to buy from year-round.
I got my costume from Pyramid Collection this year. I loved the choices and the quality. I will keep this happy pirate costume for years!
