Much of menswear is drawn directly from military uniforms, and we thought we'd bend the rules a bit to acknowledge that fact. Certainly we could have picked the cavalry - though there's not a lot of horse-riding in the military these days - but we settled on the Navy as our representative. Of course, the most iconic military-civilian crossover garment of them all came from the Navy, the Peacoat, but the driving technological needs of the military pushed menswear further in innumerable ways. Where would we be without boot-cut pants or melton wool or submariner's sweaters? Most important, though, is the blazer. It's a naval garment that many men rely on every day. Thanks, seamen!
