January Jones usually favors more classic styles when she’s playing Betty Francis on Mad Men, but at the show’s season 7 screening, the actress wore her strands in a breezy, side-slung braid that we can’t wait to try out on ourselves. With the April showers in full swing, the style is an easy alternative to a top knot, and actually works with the humidity with its effortless texture. “It’s so imperfect, that it’s perfect,” says her hairstylist Andy LeCompte. “This look leaves plenty of interpretation and can easily be translated into an everyday look with an element of surprise.”

How do you get the look for yourself? Easy! LeCompte began by working Wella’s Velvet Amplifier ($16; ulta.com) into Jones’ damp hair as a primer before blow-drying it. A spritz of the Oil Reflections product ($40; ulta.com) tamed flyaways and made her strands more manageable, and after parting her hair to the left, LeCompte began twisting two braids on either side of her head, connecting them in the back with a clear elastic. “Take the hair beneath that was not incorporated into the two other plaits, braid tightly from top to bottom, and secure with an elastic band,” he adds. “Finally, take the three separate braids, and create one large plait that feels a bit undone and messy.”

Once the style is secure, LeCompte advises pulling out a few face-framing layers, and forming a soft wave with a flat iron. A light mist of the Wella Stay Essential Finishing Spray ($15; ulta.com), while optional, gives the look extra insurance against an unexpected storm.
