When we first spied girl-about-town Rebecca Thorsen, our initial thoughts were: Holy smokes! Hello, Breck girl lookalike! And then: How can we snag her beauty secrets? The 25-year-old business development pro, who lives and works in Alexandria, is a classic blonde-haired, blue-eyed babe, with a penchant for bright lips and cat eyes. And, as a self-confessed hair-teasing addict, she knows her way around a paddle brush, too.Besides a full-time gig with her family's construction business, Becca squeezes in some fashion writing for Guest of a Guest, too. So, it goes without saying that we were stoked to get a look at her on- and off-duty wardrobes, as well as her makeup kit. And once when we sat down with her, we got all the answers to our burning beauty Qs, along with a first-person look at how she pulls off head-to-toe J.Crew one day and daytime sequins with silky track pants the next (and yes, it works!).
