Scarlett Johansson

Scarlett Johansson with one of the tightest prom updos

   Formal updos don't get much tighter than this. If you have very short hair and still want an updo at prom, the tightness could be unavoidable.

   Pulled back it looks like a basic updo from the front. From the side view (see below), you can see the structure of this hair design. Sections were pulled back and tied into a series of knots.

   It looks like Scarlett is holding everything together with lots of bobby pins. It's quite unique but does have a certain elegance to it. Cynics, however, will suggest it looks too much like a mohawk.
