Miley is sporting a rockin' updo that would be perfect for Prom.
Using an alligator clip in the rear and allowing the pieces to fall as they may, adds a touch of romantic spice. Bobby pins can used on the top to separate sections so they can cascade down into loose waves. She has some shorter layers in her cut that work perfectly for a faux short hairstyle from the front.
The front view emphasises the messy look of this style.
