Theory

Sweater Vest

The Theory Sweater Vest is your warm-weather layering hero — cool, polished, and effortlessly chic. With a classic crew neckline and relaxed fit, it’s perfect over crisp shirts or solo with shorts, jeans, or tailored trousers. Crafted from lightweight mercerized cotton spun by an Italian mill, it delivers refined texture with a breathable feel. Sophisticated and versatile, it’s the vest that does it all (and then some).

Founded on the bustling streets of New York City in 1997, Theory revolutionized contemporary fashion with the groundbreaking concept of incorporating stretch fabrics into tailored clothing, redefining the way we dress and live. Two decades on, their Manhattan-based label continues to set the standard for high-end wardrobe essentials, catering to an ambitious, urban clientele. With an unwavering commitment to excellence, Theory meticulously sources materials from the world’s finest mills and obsesses over every design detail in their in-house Atelier and Innovation Center; allowing them to craft the epitome of New York minimalism, where form meets function in perfect harmony, at the very heart of their market.
