Theory

Our Theory collection is packed with pieces exemplifying the label's contemporary take on workwear. The brand's first breakthrough, twenty years ago, came about when they developed a new, stretchy material to make trousers more comfortable while retaining a smart shape. Theory's desire was to change the way American women dressed, putting fit and feel at the forefront and creating functional, innovative and appealing garments.

Theory clothing lives up to its designers' belief that what we wear can inspire and improve the way we work and live. Expertly tailored pieces will carry you from office to lunch date, impress over drinks, and still be practical for the train journey home.

Theory womenswear includes slim-fit leggings and trousers that are easy to wear and move with your body. Lightweight dresses evoke the elegance of another era, updated with sharp and minimal details - ideal for wafting nonchalantly through a restaurant. The label's blazers and jackets bring instant confidence at work or out in town. Just shrug them on over the soft lines of a fitted cashmere jumper or airy cotton top.

True to its roots, Theory's fabrics feel comfortable against the skin and look good on. Wool, cashmere and silk crepe are soft-to-the-touch notes of luxury, while sharply tailored trousers still utilise the label's original innovative stretch fabric for comfort on the go.
