20 vintage Mardi Gras costumes

On Mardi Gras day, the best spectacle often isn't the parade rolling past but the locals on the street dressed in costumes. Some are elegant. Some are witty. And some are a bit creepy.

We dug into The Times-Picayune photo archive to find four decades of costumes, from 1946 to the late 1980s.

Maybe these photos will inspire your own costume this year.
