20 party-ready hairstyles

For hair like Paquin's, you'll need an ample supply of bobby pins. Curl and set locks with a 1" iron, which Palacios says will give hair movement, and make it easier to pin later. Once cool, shake curls out and starting at the bottom, manipulate curls and pin loose pieces as you work your way up.

Besides choosing the ideal hair color for her skintone, Adams knows how to make waves. Her hair is curled with a 1 1/4" iron, all in the same direction. "That way, it looks like finger waves," says Palacios.

The queen of cool's braid is the perfect complement to her sparkly outfit — and it's surprisingly no-fuss. To recreate, part hair slightly off-center, and tease for added texture. Use hair spray for hold, and make a loose braid over one shoulder. "They key with the braid is to start very low so it doesn't bump out," says Palacios.

"The diamond hair pin really finishes her undo," says Palacios of Stone's low bun. For your own, make a side part and divide a loose ponytail into two sections. Tuck the left section underneath, pinning it into place. Then, move the other section from right to left, tucking and pinning into place. Attach a decorative clip to the side of the updo.

Poof! Like magic, you'll have the best hair at the party when you copy the French actress' updo. Pull hair into a medium-height ponytail, tease a ton, and use lots and lots of hairspray. Then, smooth the outside of the ponytail, being careful not to take the body out. Tuck under and bobby pin into place to finish. "This is great New Year's Eve hair," says Palacios.

Sophisticated, sleek, and harking back to the 1950s, Winslet's style is all about the side-view. Part hair to one side, and bring the rest of your hair low to the nape of your neck. Then tuck under, and pin into place with bobby pins.

"Kerry's half-up, half-down 'do is perfect because it doesn't look childish, which is what sometimes happens," says Palacios. To keep your hair in adult territory, Palacios recommends side parting hair, loosely pinning up both sides, and teasing or backcombing tresses for extra volume.

The Aussie's dressed up waves resemble Amy Adams', the difference being that her curls are done in a different direction. For the texturized look, let your part fall how it may, and take a curling iron to medium-size sections of your hair. Curl some parts towards your face and others away from it.

The actress' classic look sparkles -- and not just because of her hair accessory. To copy, side part hair and pull into a low ponytail. Then, take a few random sections and pin them up for a style that's sleek in front and messy in back. Finish with a decorative clip atop the bun where it will look most tasteful.

For Wood's style, bigger is better. Center part hair and curtain bangs, literally making them appear like drapes. Begin to tease and spray hair right behind the bangs, ultimately smoothing it down with your hands and pinning the back up.
