Black socks -- plain black socks -- are so boring. First off, they're boring. Secondly, they're boring. And lastly -- and I don't want to understate this -- they're BORING. Mix it up a little. Your pants, shoes, and belt are black. Toss in a hint of color with some black argyle socks from Old Navy. Trust me. Nothing says "grrrrr!" like attractive man-ankles.
