Fairly Recent Music Video with lots of Taylor Swift Look A Likes
 

HELP! This one is driving me nuts. About a year or two ago, a two member band had a popular music video about how all the girls wanted to look like Taylor Swift. Then he falls for a girl with purple hair that looks nothing like Taylor Swift.

I believe the bands name begins with a K.
Need name of band and title of song.

I appreciate any help here.
