New York-based designer Andrew Rosen launched Theory in 1997 with a focus on creating contemporary casualwear with a distinct edge. In 2010, former Nina Ricci designer Olivier Theyskens became creative director and began to bridge the gap between designer occasionwear and the fast fashion of the high street. Expert quality, clean silhouettes and an exceptional fit underpin the men's Theory shirts collection. These understated and minimalistic pieces in muted shades are perfect for lending all ensembles a sophisticated appeal.
