Might as well check the costume stores, there are some big girls too.

As you walk into the store you see tons and tons of costumes of all shapes and sizes, most however are for kids or skinny adults and you begin thinking this is hopeless. You look over and see a cute blond in blue jeans, a t shirt with a band logo you don't recognize sitting behind the counter chewing gum and reading a teen magazine. Looking right you see the other employee, a tallish thin geeky guy in slacks and a white button up shirt standing on a chair putting a light saber on top of the shelves. You are starting to think this was a bad idea before deciding you might as well.
