New York-based fashion label Theory presents their slick and stylish new Spring/Summer 2015 lookbook, just in time for the inevitable wardrobe change. Since spring has been rather cold and summer is looking to be about the same, Theory’s new collection for men is shaping up to contain a significant amount of piece that meet the requirement for “must have.” Modeled by Mathias Lauridsen, the collection features a monochromatic offering, designed with clean lines and essential volumes. Basically a cool-guy minimalist dream. Take a look at the collection below.
