I want to know Rachel McAdams's secrets for coolness. Not only does she convey a modern vintage style in her look, but she seems to have an approachable, down-to-earth personality. Plus, I love that she isn't afraid to try new things, like this old-school teased coiffure, and some seriously punky pink hair.

This morning while filming scenes for her upcoming movie, Morning Glory, the actress wore her hair in loose waves with casual twists on the sides, showing off those multidimensional gold-toned locks. It's a perfect substitute for your typical braid-on-the-side style.

• Start with hair that's not freshly washed. Or, to "mess up" right-out-of-the-shower hair, apply a texturizing spray, like Beach Blow Texturizing Mist ($21).
• Next, twist individual pieces of hair before wrapping around a large-barreled curling iron. Leave the ends out to create a style that has a bit more of an edge, rather than a picture-perfect finish.
• Part hair how you choose, and twist sides back, anchoring them down with bobby pins. Spritz with a volumizing hairspray, and you're good to go. Try Herbal Essences Body Envy Volumizing Hairspray ($4), a budget-friendly buy.
