Theory Blazers for Men
American fashion mogul Andrew Rosen launched Theory in 1997 as a popular women's collection, offering flattering tailored trousers and sleek shirts at contemporary price points. Today, having extended into menswear, the New York-based label offers well-made everyday essentials, from crisp white shirts to slick tailored jackets, which can be worn both casually and formally.
