13 Wedding-Worthy Hairstyles

When elegance is the goal, you can't go wrong with a classic look like Once Upon A Time star Jennifer Morrison's. Bonus: It's fast! Just apply a bit of pomade to the front and underside of your hair then brush it up into a ponytail. Twist the tail into a chignon and secure with pins.

If you're wearing a formal dress, balance it out with a simple blowout and pull your hair over one shoulder like Thandie Newton did here—the style is polished but not too stuffy. To get her glossy finish, lightly mist your hair with a shine spray after you blow dry.

Feeling flirty? Try an ultra-feminine look like Gabrielle Union's and you'll bring it all night.

Just make big curls all over with an iron or hot rollers, then break them apart with your fingers. Gather your hair into a low, loose ponytail, but leave out a few layers on the sides. Tug on some hair at your crown to create volume and messiness, and then secure the style with hairspray.

Rachel Bilson's sneaky style is soft and romantic but doesn't take a ton of effort (perfect when you're running late!). To copy it, let shorter, shoulder-grazing pieces of hair hang down and pin the rest under. Gently loosen the hair around your "bob" with your fingers to create the desired shape and you're done!

For a summery, outdoor wedding try Maria Menounos's casual yet glam style. It's easy: Wrap big sections of hair around a large-barrel curling iron then brush through the waves. Make an off-center part and loosely pin up your hair. Remember, this doesn't have to look perfect. If a tendril falls down, leave it alone—it adds extra sexiness!

It's hard to look sophisticated while doing the Electric Slide, but Jessica Alba's classy style will help. First, create an ear-to-ear part about one inch back from your hairline. Comb the hair behind the part back toward the crown and tease it with a rattail comb. Smooth the top layer with a brush and pull it over your bump to hide the teasing. Secure with pins. To add some bounce, curl your ends.

No time to shampoo? No problem! Zoe Saldana's vintage-y style is easier to create if your hair is slightly dirty, since you'll get better hold. To DIY, make a middle part then tease your crown. Next, pin up all of your hair except for face-framing pieces in the front. When you're done, blast your 'do with hairspray to keep it cell phone camera-ready all night.

To give a basic updo a modern spin like Camilla Belle's, sweep your hair straight back, keeping only the sides tight as you pin them in place. Use your fingers to lift up hair in the middle and front until you start to get a messy, voluminous effect. When you have it where you want it, finish with hairspray.

Emmy Rossum's playful pony can withstand hours on the dance floor—go for it when you know the wedding DJ is going to be good.

To steal her style, French braid the sides of your hair until you get to the back of your head and tie with mini elastics. Blend the ends of the braids into the rest of your hair and make a ponytail, leaving out a big section underneath. Wrap the remaining piece around the base of the tail to hide it and pin. The finishing touch? Use a curling iron on the tail to add body.

Blake Lively's fail-proof style works anytime, any wedding. To copy her coif, apply a smoothing cream to damp hair and blow dry with a round brush. Then, pin back the front half of your hair with a bobby pin or pretty barrette and you're good to go.
