Creating contemporary clothing with a distinct edge, native New Yorker Andrew Rosen launched Theory in 1997 with a focus on relaxed silhouettes and understated details.

In September 2010, Olivier Theyskens was appointed Creative Director, marking a turning point for the brand. Building upon the mantra of creating clothing for everyday life that bridges the gap between high-end and high street, Theory offers well-rounded collections that feature everything from sharp tailoring and timeless occasion wear to pared-back basics. Expect to see sleek city separates sitting alongside luxe eveningwear – think classic wool coats, cashmere jumpers, silk blouses, structured leather bags, and fluid slip dresses.
