Women’s Good Collection
Theory For Good
Twenty years ago, a pair of pants changed the way American women dress. Recognizing the need for clothes that felt great and fit perfectly, we developed an innovative stretch fabric that would dramatically improve a pant’s performance. These pants had the power to make women feel confident, smart, and stylish. Never before had American sportswear been so easy to wear to work and everywhere else.
When Theory for men was established, similar foundation principles were used, so that they, too, could get dressed in innovative, highly functional, and stylish clothes.
Watch award-winning filmmakers Jun Diaz and N + N Films's tribute to our 20-year history, New York City heritage, and vision for the future.
We believe cool, expertly tailored pieces made from the best materials have the power to change the way we feel, improve the way we work, and inspire the way we live.
Our commitment to design, fit, and construction ensures exceptional comfort and quality.
We source our materials from the best mills in the world and test every fabric for its hand-feel, durability, and design.
Versatile, sophisticated, and easy to wear, our seasonal collections are designed with purpose.
We are committed to making a positive impact on the people who wear our clothes, our industry, and our planet, beginning with our Good fabrics.
