Complement a pretty gown with an equally sweet hairdo like Gwyneth Paltrow's. A simple change in your hair part breathes new life into your tresses (Paltrow's side-swept style is flattering for most face shapes). Clipping it back will keep your new part in place -- try a pretty pin for a girly touch.

Get her look: Make a deep side part along the arch of one brow and blow-dry hair straight using a paddle brush. Smooth ends with a smoothing serum and secure bangs behind the ear with bobby pins.
