Swift’s sexiest look yet?

Taylor causes some double takes at the IHeart Radio festival

Taylor Swift is shaking up more than just her musical style. The country singer turned pop star also updated her style from pretty and proper to down right sexy.

The 24-year-old donned a white bandeau top and a skin-tight red skirt at the iHeartRadio Musical Festival in Las Vegas. She completed her midriff-baring look with strappy heals and bright-red lipstick.

Swift performed her new single "Shake it Off" off of her upcoming pop album 1989 due October 27.

She was the opening act for the Las Vegas festival on Friday. Other performers included Coldplay, Nicki Minaj, Usher and Ariana Grande.
