The story of Theory started with one simple garment: trousers. Two decades ago, the brand recognised the need for a pair that fit perfectly and felt empowering. In response, it created its very own innovative stretch fabric and began crafting pieces that were smart, comfortable and could keep up with a busy lifestyle. The company is still at it today and has expanded to offer a comprehensive line of women's Theory clothing that makes it easy to fill up your wardrobe.

Block colours and contemporary cuts are a common theme in Theory ladies' fashion, as you'll see when you dive into our selection of turtleneck jumpers and high-rise culottes. We've also got irresistibly cosy fabrics: from super-soft cashmere to smooth cotton jersey, our choices will be kind to skin – and the planet, too. Look out for our green Project Earth stamp across the collection, letting you know about a product's planet-conscious practices.

Step seamlessly from the boardroom to the bar in a jet-black jumpsuit with statement wide legs. Why not choose an asymmetric midi skirt crafted from smooth satin to flaunt your ultra-modern tastes? Pair it with a v-neck silk top to complete your stand-out silhouette.
