The 15 Best Fashion Moments at the EMAs

Miley Cyrus, Katy Perry, Rita Ora, and Iggy Azalea did NOT disappoint in the fashion department—check out what they wore to the show, plus all the other crazy looks of the night!

Ariana Grande looked super-cute in a nude and black lace cocktail dress from the Resort 2012 MIKAEL D Collection. She even belted out a few songs impromptu style during the show!

Would you expect anything less MAJOR from Miley?

But then there was this silver performance moment.

And last, but not least, her arrival outfit with Biggie and Tupac's faces on it—those boots though.

Aussie rapper Iggy Azalea's wardrobe malfunction was the result of not one but two SERIOUS thigh-high slits. What's a good red carpet without a bit of accidental flashing though?

At least her futuristic two piece didn't backfire on her as well?

Katy Perry looked demure in comparison to Iggy in this retro, mint green, satin dress. She also showed off a pretty rock, prompting everyone to speculate whether or not it was from beau John Mayer.

Later she changed into a sheer black dress with a super-high pony.

And a crazy embellished bodysuit to perform...

Icona Pop closed the show with "I Love It," but not before hitting the carpet in black and white coordinated outfits.

Fashion journalist Louise Roe went for bright, tribal-esque Mara Hoffman separates.

Also opting for a peek-a-boo skin look was Ellie Goulding, who rocked Dolce&Gabbana for the occasion.

And Laura Whitmore opted for a structured Fyodor Golan mini with peplum and embroidered details.

Shanina Shaik was gorge in gold. The model arrived on the arm of Tyson Beckford.

But our favorite look of the night belonged to the lovely Rita Ora in this black halter dress. Straight sex appeal with a dose of chic. Loves it!
