People
As part of our mission at Theory, we believe the clothes we make matter because of the people who wear them. With human empowerment as a core value of our company, we continuously look for new ways to support and elevate those around us, be they our employees, customers, or local donation partners.

Diversity and Inclusion
Product
We’re building sustainability into our DNA beginning with raw materials. Our most-used fibers—cotton, wool, and linen—are sourced from environmentally and socially responsible farms. These fibers are transformed into our signature Good fabrics by mills focused on reducing the impact of their manufacturing processes. We’re committed to reach 100% traceability on signature fabrics by 2025.

Good Cotton
Good Wool
Theory for Good Circle
Our take-back program keeps preloved Theory garments out of landfills by repairing and donating them to ensure our garments have a second life. Since the program’s inception, 12,251 garments (and counting) have been repaired, washed, and donated to our charity partners.
How it Works
- Drop off your gently used Theory items in store or email us (with subject line TFGC Garments) to request a free shipping label and send them in.
- Our team will sort, repair, and clean your garments.
- Your donations will be sent to one of our local partners: The Fresh Air Fund, The Center, or Street Soccer.

A series of discussions putting scalable sustainability solutions into action. Held in partnership with The Council of Fashion Designers of America with support from the United Nations Fashion & Lifestyle Network, these events provide a forum for the New York fashion community to be in conversation with industry-leading experts across traceability, innovation, circularity, and more.

Good Linen
Woven exclusively for Theory by the Marini & Cecconi Mill in Prato, Italy for 25 years, Good Linen is crafted with three fibers: linen sourced from France, viscose created from waste cotton fibers, and certified recycled elastane.
The Farms
Good Linen continues a centuries-long agricultural tradition of flax farming that requires little water and provides natural soil fertilization. Our Good Linen fabric is made from fibers from the inside of the flax plant, all sourced from five farms located in the Normandy region in France. These farms take a zero-waste approach to flax production, putting every part of the plant to use-from the seeds which are pressed for oil to the stem used to make particleboard.
The Mill
Family owned and operated since 1945, the Marini & Cecconi Mill is one of the first signatories of the Greenpeace Detox Program geared towards removing hazardous chemicals from the production process. 50% of the water used in the production process is recycled thanks to GIDA, a special water purification system in Prato. The company also uses electricity generated from a photovoltaic system which converts thermal energy into electricity.
The Atelier
After receiving Good Linen from Prato, our atelier and innovation center in Manhattan's Meatpacking District skillfully crafts the initial prototypes of our garments. Used in a wide range of silhouettes from blazers and trousers to dresses and tops, this airy, light fabric is preferred for its excellent stretch and recovery.

Community
To step beyond style, we need to understand the entire life cycle of our clothing and how it can empower our communities, especially the next generation. From our resume workshop with The Fresh Air Fund to educational tours hosted at our Design and Innovation center, we encourage everyone at Theory to participate in community outreach.
Good Cotton
Good Cotton is crafted with extra long staple SUPIMA® cotton. We’ve partnered with Oritain, a company that uses forensic science to verify our cotton fibers from the farm to the factory in Italy.
The Farms
Less than 1% of the world’s cotton crop is SUPIMA®. Ours is grown on farms in Southwestern and Western United States like the Boswell farm in California which practices precision agriculture—a technique that maximizes output and quality while minimizing resource usage. These farms rotate between cotton and food crops to maintain the health of the land.
The Mill
A fifth generation family business, the Albini mill in Bergamo, Italy has reduced its annual energy usage by 8,000,000 kWh, which is equivalent to powering 2,700 households for an entire year. The mill's annual water consumption has been cut by 46,000 m3, which is enough to fill 18 Olympic size swimming pools.
The Atelier
Transported to our atelier and innovation center in Manhattan’s Meatpacking District, Good Cotton is tailored into the intentionally designed prototypes of shirts and dresses that are known for their crisp look, subtle stretch, and year-round appeal.

Good Wool
Our Good Wool is sourced from responsible farms in Australia and woven by an eco-conscious mill in Biella, Italy.
The Farms
Good Wool begins with free-roaming merino sheep at farms like the Beaufront farm in Tasmania, Australia, which follows strict land management and environmental conservation programs. This non-mulesing farm shears its sheep with the utmost care and preserves native grasslands with strategic grazing practices.
The Mill
Good Wool is woven at the Tollegno 1900 mill in Biella, Italy, which self-produces 35% of its energy using solar panels and water turbines powered by the neighboring Cervo river. All alpine water used to dye and finish Good Wool is purified and returned to its source, while 40% is reused.
The Atelier
After it’s expertly finished in Biella, Good Wool arrives at our atelier and innovation center in Manhattan’s Meatpacking District. Prized for its lightness and smooth hand feel, Good Wool is carefully tailored into prototypes of our blazers, trousers, and more.
