Theory: Defining the New Modern

Founded by Andrew Rosen in 1997, Theory revolutionized the contemporary market with its concept of the urban uniform, a modern edit of elevated essentials.

The Fast Retailing acquisition of Theory in 2004 spurred global expansion of the brand; today, Theory operates 221 freestanding stores worldwide. The launch of e-commerce in 2010 and collaborative relationships with department and specialty stores continue to position Theory as a continually expanding international omnichannel phenomenon.

A leader in Fast Retailing Group's dossier, Theory balances luxury with accessibility in collections with integrity known for their precisely tailored silhouettes and exceptional fabrics.

Theory is an equal opportunity employer and does not discriminate in regards to race, gender, religion, age, national origin, citizenship status, disability, qualified veteran status, marital status, or sexual orientation.
