Beachy waves aren't just for the summer time. And at last night's GQ "Men of the Year" Party, Amanda Seyfried showed that this classic 'do works in fall, too.

The "Mama Mia!" star channeled the '60s with her wavy strands, pulling back pieces at the crown to show off her trademark fresh face.

To mimic Seyfried's perfect beachy look, celebrity stylist Danielle Caputo suggests curling hair away from the face. "It creates a windswept effect and helps keep it from falling forward," she said. "Use a salt-water spray (which helps create that piece-y texture) at the roots and then all over to add texture."
