"I've got my weekend uniform down to a science: a Prism bathing suit, One Teaspoon shorts, and a good, old-fashioned tank top," says Wasson. She's modeled in ads for Michael Kors and H&M, appeared in the Pirelli calendar, and spent her whole life riding horses, surfing, and being outside—and her weekend style is as bohemian as it is stylish.
"Sometimes I wear Vans, but mostly I'm in cowboy boots. I'm a big believer in wash-and-wear hair. I like Wen by Chaz Dean Cleansing Conditioner because it's super-rich, then some Rose Veil Hair Serum. I love how my hair gets wild after a day outside, so I'll spray in a little leave-in conditioner and let it do its thing. At night, I'll add Chanel bronzer and RMS mascara."
