Whether you're getting dolled up for a night of clubbing or you want to look like that's where you're heading, take a page from celebs who live to take risks that will leave fashion police and style magazine editors asking for more. Dressing up your hairstyle doesn't mean sacrificing hours or buying enough styling products to set up shop. There's only one thing to make sure of when you pick a dress-up do: The style has to hold up. Who knows what kinds of shenanigans your glam hairdo may provoke once you let loose?
Behold the Bob
If you saw a photo of Emma Watson walking the Red Carpet at the final Harry Potter film debut in New York, you know the girl has gone pixie glam like Michelle Williams, Carey Mulligan and other starlets. To match Emma's edgy gold gown, her hair stylist pulled off a sleek bob that would shame the most stylish 1920s flapper. The secret to pulling off short-short dress-up hair is making certain your hair shines thanks to the right gel and shine products. A rhinestone clip may be all you need to add some glitz. Play up your eyes with smoky colors and knock 'em dead.
From Kim Basinger to Kate Winslet, emulating old-world Hollywood hairstyle hotness means taking a page from Veronica Lake, the screen siren of the 1940s. Pull back one side of the hair behind your ears to go flirty while allowing the other to cascade down your face and shoulder like a waterfall. While this hairstyle works best with a body-hugging sheath (forget "Gone With the Wind" ball gowns, please), no compromising on those lips: Choose the boldest red you own. A girl can't smolder when she puckers in pink.
Make a Mess
Some AAA-hot hairstyles rely on messiness to stop traffic. Use your go-to mousse or styling product to add volume to clean hair before picking your weapon of choice to curl it -- hot rollers, curling wand or Velcro rollers. When you're ready to style, forget the brush and comb. Bend over and shake out your hair. Use clips and pins to pull your mane into a messy flat French twist or low bun, making certain a profusion of tendrils fall around your face and neck. Don't look like you just got out of bed? More tendrils, please.
Bobs, buns and braids come and go, but traditional up-sweeps are always the right dress-up hairstyle for big occasions. You don't need long hair to pull this off, either. That's why God made hairpieces. A short or long attachment can turn you into Kim Kardashian channeling a Greek goddess or Penelope Cruz sporting so many cascading curls, Marie Antoinette would be jealous. Updos make a great canvas for waterfall earrings, so even if you don't have jeweler Neal Lane on speed dial, you can still accessorize your bouffant pile-up with thick chunks of glitter hovering over your shoulders.
