Today I was dressed as a skeleton princess.
It seems to have sold out of a lot of sizes (only s and m left) but keep an eye out as they do restock (not always though): http://www.modcloth.com/shop/pullovers-sweaters/show-and-skeleton-sweater?
If you're on the thin side though, you could probably easily find another and much cheaper too. But for bigger people, I find these pretty rare sadly.
