Native New Yorker Andrew Rosen launched Theory in 1997 with a focus on creating contemporary casualwear with a distinct edge. The label combines well-tailored seperates with easy to wear party dresses for a perfectly rounded collection. September 2010 marked a turning point for Theory when Olivier Theyskens, former Nina Ricci designer, was appointed creative director. Theyskens plans to build upon the Theory mantra of creative clothes for everyday life that bridge the gap between designer occasion-wear and fast-fashion of the high street. Head to Theory for sharply cut, timeless designs that are perfect for all occasions.
