Last night’s American Music Awards were filled with a lot of the sartorial excitement we’ve come to expect from these types of shows: Miley wore underwear onstage (cat-themed, to be precise!), Jennifer Lopez paid tribute to Celia Cruz in a sparkly bat-like muumuu that became a rainbow salsa getup and then a fringed leotard, and Katy Perry chose a racially insensitive costume for her opening act, à la Selena Gomez. But the red carpet was filled with its own style gems, including Nicole Richie in an underwear-defying dress, R. Kelly in a man-tunic, and Miley Cyrus in something completely normal. See the best, worst, and most outrageous looks in our slideshow.
