Eileen Fisher is the founder and co-chief executive of Eileen Fisher, Inc, the design company known for creating simple, timeless garments, where she also serves as the chairwoman. Fisher ventured into clothing design in 1984. Her original concept — pieces that work together to help women get dressed easily — still defines the company’s collections. In 2009 the company started a take-back program — part of a circular system designed to preserve the value of the brand’s clothes at every stage, in any condition. The company has taken back over 1.2 million garments to date. In 2016, the company became one of the largest women’s fashion companies to be certified a B Corporation, voluntarily meeting high criteria for social and environmental performance, accountability and transparency.

In June 2019, Fisher received the Positive Change Award from the Council of Fashion Designers of America (CFDA). In April 2019, she was honored as Designer of the Year by the American Apparel & Footwear Association.
