AMAs 2015: Every single star look

The music industry celebrated in true style at the AMAs 2015 last night.
There was a lot to talk about - Charlie Puth and Meghan Trainor enjoyed a steamy snog on stage; Kendall Jenner has bangs and we lost our shit over the return of Alanis Morissette's You Oughta Know with special guest Demi Lovato.
Then there were the outfits... See who wore what below:
