I've been a "black shoes with everything except brown slacks" kind of guy all my life. Should I be a "brown shoes with everything except black slacks" kind of guy? A lot of very smart posters seem to be rocking mostly browns for non-formal attire. Does brown really look that good with navy and gray? I'd love to expand my shoes wearing range. What do I need to know to pull off more browns (light chili, chocolate suede, etc)?
