Seyfried is a classic blonde bombshell, and she pulls off yet another stunning look: the classy side part with glam waves. Create voluminous waves with hot rollers, then pull back the side with less hair, and secure it with a sparkly clip or barrette. Accessories add elegance to otherwise simple hairstyles.

Cyrus' no-fuss side-swept ponytail makes any outfit look polished and pulled together. While the ponytail itself is down-to-earth and practical, the girly tendrils around her face create a glamorous effect. After securing curls into a ponytail, pull out a few face-framing pieces, apply a touch of styling gel (try Kiehl's Clean Hold Styling Gel, $15), and wrap the pieces around your finger to form them around your face.

Swift is "fearless" when it comes to experimenting with different hairstyles, and she gets it right with this side-swept updo. To get Swift's thick bun, run volumizing foam (try Ojon Conditioning Volumizing Foam, $22) through your hair with before blow drying, then curl the bottom half of your hair using a one-inch iron. Secure the curls into a low side pony, pulling the curls only half way through on your last wrap around. Pin any loose ends to perfect the shape.

Menounos' side-swept curls look strong enough to last all day, yet soft enough to touch. To get this look, curl your hair using a large barrel curling iron (you want big curls, not tight tendrils). Then sweep the mass of curls over one shoulder without separating them, and spritz with hairspray for hold (try John Frieda Luxurious Volume All Out Hold Hairspray, $5.99).

Theron's updo is the epitome of elegant. Loose curls create a soft, flowing effect when tucked to the side. To get this look, use hot rollers, then run your fingers through the curls to break them up. Pull your hair gently to the side of your head, and secure into place using clear elastic. The key to achieving the elegant finish is leaving the front tendrils loose and wavy.
