Check out Tyler Riggs and Boris Kolesnikov of Red Models in Vogue Pelle. I love leggings for men during both spring and fall, but I especially like when they are paired with coats and other fall accessories. Visually, I like the idea of having different layers (ie: a combination; give or take of scarves, button downs, waistcoats, long and short sleeved tees) falling at different heights on top of a simple clean silhouette created by leggings. Also, for those uncertain about leggings, coats take some of the edge off shortening the visibility of the leggings. If you have missed one of my million references, check out these if you want the leggings look.
