How cute is this twist on a classic chignon? I'm loving the look on Olivia, it's simple yet surprising.
(And a great "go-to" hairstyle for the holidays!)

To get-the-look:

First, smooth your locks into a low ponytail and secure with a clear (or discreet) elastic. Next, tuck under the ends, rolling your hair into a ball. Finally, secure your roll under the base of your ponytail. To finish, free a small lock of hair and wrap it around to hide any visible pins.

Will you be experimenting with Olivia's latest look?

Pull out your ruler and pencil sharpener, ladies — super-high buns are back.

Personally, I consider myself to be a low-bun kind of girl, but both Rachel Bilson's and Cameron Diaz's latest looks provide plenty of reasons to convert.

Do you like high buns? Would/do you wear them?
