I always find it difficult to match socks to shoes/pants. In general, I try to keep my shoes and socks similar colors, which is really easy when you wear black shoes, dark socks, and charcoal pants. But what happens when I wear olive pants with brown shoes? Or with black shoes? How can I mix in creative socks (argyle, etc.) without looking tacky? What if I have no socks the EXACT color of my brown shoes? There must be some guidelines on what works and what does not, especially when not wearing the typical conservative dark pants with black shoes. Any tips?
