If you haven't already guessed, this back-of-the-head picture happens to be Julianne Hough, who, last time we checked, had pretty short hair.

Short hair = no bueno for one of those fancy braided bun hairstyles that were cropping up all over the NYFW runways a couple weeks ago, right? Well, now that we mention it, Julianne has us thinking differently.

The blonde actress stepped out last night at Escada and W Magazine's celebration of Cool Earth event, looking chic in an all-black ensemble and a sophisticated topknot. But what looked like all business in the front, turned out to be all party in the back. Julianne (or her hair stylist, or both) figured out the perfect way to work the braided bun style into her short hair.

Julianne started her the nape of her neck with a French braid, and then worked up to a smaller braid as her strands got too short for the French. She topped it all off with a bun piled on top of her head. We're kind of loving this genius style, making it a perfect contender for our look of the week.
