Poll: Who Put Their Back Into It Best at the Grammys?

Just like you don't judge a book by its cover, it's wise not to judge a dress by just glancing at its front. We took an all-angles look at the red carpet at last night's Grammy Awards so we could round up the four best backside views (and let's just say there was plenty of competition).

Katy Perry, in Zuhair Murad, showed skin not just with her bare back but with the sheer crystal-embellished dress itself. Never one to shy away from skin, Miley Cyrus used strategically placed cutouts and a backless Alexandre Vauthier gown to do the job, just as Katharine McPhee did in a sexy coral Emilio Pucci gown. Ariana Grande, however, used unique cutouts on her white Versace gown to show off her backside.

So, whose backless look was sexiest? Take a closer look, and then vote below!
