We get it — all those Halloween parties you mentally declined a month ago are coming up tonight, or tomorrow, and suddenly you're itching to go out. Only one problem: you don't have a costume. Before you run out and spend two hours waiting in line at a party store, or give up entirely, take a look through this list we've put together. It plumbs some of hip-hop and R&B's most iconic — both older and more recent — moments for inspiration for simple yet effective costumes. They should be easy to put together (three items or less), yet obscure enough that you won't have to twin with anyone. And above all, they're low-key, so you won't look like an idiot on your way home.
