Rumer Willis's Met Gala look was traditionally elegant in almost every way. Stylist Charles Baker Strahan gave her a chic updo, and her creamy complexion was flawless. Like we said, elegant — but then we took a look at her manicure. Four nails were painted black, with her pinky accented with a glossy red lacquer. It's the kind of tiny detail that updates an otherwise classic look with just a little unexpected flair. Cute!
