Theory Fashion

Created for you, crafted for good. Theory began with two ideas in mind: to create clothing that feels great and fits perfectly, and to do so in such a way that makes a positive impact on those who wear Theory clothing, as well as the fashion industry, and the planet. In the decades since its inception, Theory has proven itself a tour de force - a veritable couturier of cool understated style, and a leader in environmental and social responsibility. And though the brand is constantly evolving, Theory remains true to its roots with apparel that is chic, sophisticated, and comfortable - and practices that flawlessly balance commerce with accountability.

Theory Men. Effortlessly elegant, Theory apparel for men strikes a balance between classic and cutting edge - delivering looks that are chic, elevated, and as easy to wear to the office as they are on a date, to a game, or to a dinner party. With suits and separates you can mix and match, our newest collection offers an ease that comes from knowing you look as good as you feel.  

Theory Women's Clothing. Simple, iconic, and luxe on every level, Theory fashions for women are modern classics designed for every facet of your life. With looks you can wear to the office and the opera, play dates and dinner dates, our newest collection of Theory clothing makes it easy to dress stylishly for the day - no matter what it may bring. Looking for petite sizes? Shop our Theory petite collection.

Theory Dresses. With work-ready silhouettes and weekend-ready designs, Theory makes stylish one-step dressing easy every day of the week. Featuring shifts and midis that look just as chic with or without a blazer to t-shirt dresses and minis you can wear with your favorite sneakers, sandals, or booties, our newest collection of dresses from the Theory clothing brand just might change your life.  

Theory Suits. Featuring fabrics that stretch with you but never stretch out, suits and suit separates from Theory deliver all-day style and comfort you can feel confident about. In classic cuts and flattering fits for both men and women, our newest selection makes it easy to dress to impress and dress for yourself.
