This Fashionable Brooklynite Nails The Active (Life)Style

While we’d like to think we’ve got this whole adult thing down pat, we have to admit: Juggling a full-time job, staying fit, and finding time for both friends and hobbies sometimes seems near impossible. But, not so, says Camilla Mayer, cofounder of creative agency and style blog Open Haus Collective. While her high-powered position places her at the helm of digital strategy and content creation for fashion clients, her off-duty lifestyle plays just as big a role. She spends after-hours biking around her Bushwick 'hood, hitting up the occasional warehouse party with her girls, and, despite her techy role, writing in her journal on a daily basis. (Yes, with pen and paper.)

So, we tagged along for an action-packed day in Mayer's life to see how her fast-paced job and free time go hand in hand. One secret she was happy to spill? How she wears her versatile lululemon gear both in the gym and out, effortlessly incorporating her favorite sleek sports bra and running tights into three unique outfits throughout her day. Ahead, get this fashion phenom's play-by-play and lifestyle advice — and master her laid-back, athletic style while you're at it.
