Theory Wardrobe
Elevated essentials, designed for a lifetime.
A well-curated wardrobe starts with versatile, indispensable pieces. Defined by precise tailoring perfected in our New York atelier and premium fabrics sourced from the world’s best mills, the styles in our Theory Wardrobe edit are our most sought-after pieces. Available year round, these bestsellers simplify the act of getting dressed, allowing you to focus on what matters most—achieving your goals and aiming for perfection.
Your Go-To Tee
Lightweight with a trim fit, our Precise Tee is crafted with breathable, silky Egyptian cotton. A dressy look and laid-back feel make it the ideal tee to pair with a blazer.
The Performance Suit
Invest in a suit that puts in overtime. With a softly structured fit, the Clinton Blazer is the perfect compliment to our sharp Zaine Trouser—both in a breathable, machine-washable fabric with stretch.
Why We Love: Precision Ponte
Engineered for comfort and a crisp look around the clock, our breathable stretch Precision Ponte boasts wrinkle resistance and durability. Machine washable and quick drying, this performance fabric wicks moisture and dries quickly.
The Classic Suit
Our traditional Chambers Blazer and streamlined Mayer Trouser make a solid first impression. This suit is crafted with a fine, medium-weight Italian wool that boasts inherent moisture control, wrinkle resistance, and just the right amount of stretch.
A Refined Polo
A refined take on the quintessential polo, this easy-to-style base layer is made with subtly textured Peruvian cotton.
A Crisp Button-Up
Detailed with darts for a refined fit and an easy-to-tuck-in hem, our Sylvain Shirt is the only button-up you’ll need.
Why We Love: 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 farms in the US to the Albini mill in Bergamo, Italy.
Non-Denim Denim
Like denim, but better, our Raffi 5-Pocket Trouser is an elevated take on jeans with water-resistance and four-way stretch for easy movement.
