Theory is launching its first ever e-commerce site this spring. Fans will not only be able to buy the clothes, they'll also get expert advice on exactly how to wear them from seventeen top stylists like Andrea Lieberman, Isabel Dupre, Kate Young, Tina Chai, and Jessica Diehl. The stylists poured over the collection, mixing, matching and layering their favorite pieces into countless unique looks for Theory's Fashion Insider campaign. The result? Tons of outfit inspiration and a shopping experience that is tailored—just like Theory! Browse the collection by stylist, see behind-the-scenes videos of them at work and shop your favorite looks head-to-toe. Check back this Wednesday for an exclusive 2-day preview of the yet-to-launch site. You'll be the first to shop the spring collection and have a chance to win a limited-edition Fashion Insider T-shirt!
