There's a subtle trick to reviving old styles. It needs to be reminiscent of yesterday but somehow feel very much "right now." Which is exactly what we're seeing with the surge of olive drab pants popping up seemingly everywhere—from cult designer labels to more accessible mass brands. It makes sense. A pair of army green pants, cut from a comfortable cotton, should be a staple of any stylish man's wardrobe. Casual, versatile and unmistakably classic, they're as adaptable as your everyday tan chinos but seem a whole lot cooler thanks to the subtle military vibes they give off. While it's certainly a classic color, it works as a modern neutral. The richness of the green color just seems to pair better with other colors, from shades of blue and crisp white to basic black. So if you don't have a pair, get one (and soon) because you'll be wearing the hell out of them, trust us.
