Men's Suits
Built on our foundational tenets of fit, fabric, and functionality, our men’s suits are designed to change the way we feel and improve the way we work. Meticulously constructed to create a superior fit and produced using the industry’s finest, most enduring fabrics, each suiting piece—whether worn together or separately—epitomizes American sportswear by marrying a timeless appeal with modern mix-and-match versatility. All Theory men’s suits are sold as separates to allow our customer to customize his wardrobe with the essential pieces and silhouettes that best correspond to his person style—be it the structured single-breasted blazer for work or a formal occasion, tailored yet casual pants for WFH, the ubiquitous black suit, a sportier navy suit, or a modern slim-fit suit. Our renowned suits span a range of fits from classic, such as the Chambers blazer and Mayer pant, to relaxed silhouettes, such as the Aiden jacket and Hunter pant. Our fabrics offering is just as versatile. If you’re looking for a timeless, all-seasons suit, look to Good Wool: responsibly crafted in ultra-fine merino wool woven with ample stretch for a soft, lightweight feel that’s wearable year-round and resists wrinkles. For something sportier that is comfortable enough for an on-the-go lifestyle, our lightweight Precision Tech performance fabric is as functional as it is stylish, with four-way stretch for easy movement and shape retention.
