Theory Women's Trousers

Turn to our collection of women's Theory trousers for what may become your most comfortable pair of bottoms. The American brand was established in 1997 and set out to create clothes that prioritised fit above all else, leading it to invent an innovative stretch fabric that flexes with your body as you move. 

In our selection, you'll find Theory wool trousers that create an instantly smart aesthetic. We have tailored designs with plenty of discreet functional details, such as concealed fastenings and buttoned jet pockets. Darts and pressed creases make for a flattering shape. Take your pick from a wide variety of shades from classic go-with-everything hues (think deep navy and charcoal grey) as well as statement-makers like light blue or rust.

Theory black trousers are your versatile everyday heroes. Discover options crafted from cotton-rich materials that are soft and ultra-breathable, as well as rebellious leather styles for a dose of attitude. Regular fits are relaxed and easy to wear, while high-rise waists keep things sleek and streamlined. On warmer days, opt for shorter ankle-grazer lengths that feel breezy and lightweight, especially when teamed with floaty blouses and silk shirts. Experiment with your casual outfits by choosing garments with unexpected additions – leg slits or contrast tonal stitching, for example.
