Founded in 1997 by Andrew Rosen – an executive at Calvin Klein – and Israeli designer Elie Tahari, Theory is a considered New York brand based on the iconic wardrobe staples you turn to again and again. Built around the brand’s signature stretch trousers – designed for the perfect fit, superior comfort and versatility – a women’s capsule collection of sleek dresses and tailored separates with textural accents and soft knits redefines the gap between work and weekend style. In a quietly sophisticated palette of black, grey and neutrals, the result is a contemporary aesthetic that informs your year-round wardrobe.
