Reese Witherspoon's simple bun may be a classic, but her front pouf adds an adorable touch. With added height on top, this style looks great on round face shapes.

Get her look: A day-old hair works best. To create the pouf, tease the front section of your hair, then pin back on top of the head using bobby pins. Next, pull the rest of the hair into a high ponytail and twist into a bun. Secure with bobby pins. Spritz all over with hairspray for hold.

Anne Hathaway is sweetness personified with her messy-in-a-cute-way 60s' ponytail and geeky glasses. Who says a low-maintenance look can't be chic?

Get her look: Apply volumizing mousse to towel-dried hair, then blow-dry with a large round brush. Curl hair from ear-level down using a curling iron. Comb through to loosen the curls, then backcomb layers around the nape to add fullness.

Have naturally wavy hair? Play up the texture with a spritz of sea salt spray for that effortless untamed bob a la Keira Knightley.
