A straight, long bob or "lob" with plenty of volume and angled bangs is equal parts sophisticated and youthful. Here's how to replicate the stylish 'do Reese Witherspoon sports at the "Water for Elephants" UK premiere.

Get her look: Apply mousse to damp hair, working from the roots to ends. Make a side part and blow-dry hair, lifting roots for added volume. Blow-dry bangs to one side using a round brush.

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.

Love the '60s go-go girl vibe that Reese Witherspoon channels at the 2011 Oscars! The key to rocking her mod ponytail is volume. Here's how to get it: Get her look: Apply a volumizing product to wet hair and blow-dry with a large round brush. Wrap the ends of hair around the barrel of a 1 1/2-inch curling iron to create curls then tease the roots to add volume on top. Sweep hair back at the crown of the head, and secure in place. Mist hairspray all over for hold.

Play peek-a-boo with flirty eye-skimming bangs! To replicate Reese Witherspoon's style, ask your stylist for angled bangs that start above the brow and fall over the cheek.

Get her look: Make a side part and blow-dry bangs first using a flat brush while pointing the dryer down over the head. Blow-dry the rest of the hair straight, then finish with a straightening iron.

Soft, piecey curls and flirty eye-skimming bangs frame Reese Witherspoon's heart-shaped face beautifully.

Get her look: Start by blow-drying the bangs, pointing the nozzle of the dryer down while holding the bangs taut with your fingers. To re-create Reese Witherspoon's curls, wrap sections of hair from mid-shaft to the ends around a medium-barrel curling iron. Spread a little wax between hands and gently finger-comb through to break up the curls for a piecey finish.
