The red carpet was decidedly a bit edgy and almost casual, but we loved the mix of gowns, minidresses and pants. There's nothing quite like a musical award show to let everyone show off their true style (Case in point: the Grammys!).
Swift opened the show with a performance of her smash hit "Blank Space" before winning the award for Best International Female, and Ed Sheeran took home the award for Best British Male. Click through above to see what everyone wore on the red carpet!
