It's no surprise that Miley Cyrus' MTV EMA look was what everyone was talking about. The fashion tribute to Notorious BIG and Tupac was paired with thigh-high peep-toe boots and as always, left little to the imagination. Katy Perry went conservative in a form fitting Zac Posen dress and later heated things up with a second outfit for her performance of "Unconditionally." Ariana Grande rocked a black and white lace cocktail dress, completing the look with a chic high ponytail. The most daring look of the night belonged to Australian rapper Iggy Azalea, who looked ready for a wardrobe malfunction in her leg-baring gown.
