Theory: the phenomenon better known as “everyone’s favorite black pants.”

Theory is built on fit. Modern classics made from the latest fabrics and spun with old world craftsmanship and attention to detail. Using just enough stretch, Theory flatters and hugs in all the right places.

Superminimalist, silhouette slimming, smart and fashion savvy basics and suiting. Easy to mix and match, Theory has two qualities we adore—simplicity and longevity.
