When we saw how hot Rihanna looked in her tuxedo at the Metropolitan Museum of Art Costume Institute gala on Monday night, we were reminded that she's certainly not the first chica to turn fancy menswear into an androgynous fashion statement. Here are some of our favorite ladies to go black-tie in the public eye:
Celine Dion: For the 1999 Academy Awards, the diva mixed things up by opting for white and then, apparently styled by by Kris Kross, she wore the jacket backwards! Let's not even get started on the hat.
Madonna: Of course, what Madonna wore at the 2005 VMAs was greatly overshadowed by the fact that she made out with Britney Spears and Christina Aguilera.
Angelina Jolie: Angie can be counted on for her edgy red carpet style, and she's embraced the risky tux look more than once: First at the Oscars in 2001 and again this year, when she wore a winter-white tux to the Berlin premiere of "The Curious Case of Benjamin Button."
Diane Keaton: Since making menswear hip in "Annie Hall," Diane has donned tuxes at many a formal occasion. She outdid all the men on the red carpet at the 2004 Oscars, where she wore tails, a waistcoat, a long tie, gloves, a watch chain and top hat.
Britney Spears: OK, in the video for "Me Against the Music," both Madonna and Brit are wearing suits, not tuxedos, but since we're not planning on doing this list again anytime soon, they might as well get a shout-out now for their gender-bending getups.
Marlene Dietrich: We're pretty sure all of the ladies above (or at least their stylists) owe some inspiration to this silver-screen sexpot, who sizzled in a top hat and tails in the 1930 film "Morocco."
