Here's an effortlessly elegant and versatile updo that'll take you from work to play: Take a cue from the ever-graceful ingenue Natalie Portman, who wears her tresses slicked back into a sophisticated bun at the nape. This off-the-face style lets your features take centerstage, so top it off with eyeliner and extra lashings of mascara to make your eyes pop.

Get her look: Apply a straightening balm to towel-dried hair and blow-dry with a round brush. Make a deep side part, then smooth hair back into a low ponytail with a boar-bristle brush for a bump-free finish. Tuck the tail under the pony to make a bun and secure with a clear elastic. Wrap the ends around the base of the bun and bobby-pin in place under the bun. Finish by styling bangs to the side behind the ear.
