I happened to put on a gray shirt this morning, and as I perused my sock drawer, nothing jumped out at me as being quite perfect. That is, until I came across this black and gray argyle pair which made a perfect match with the monochromatic theme I found myself accidentally rolling with.
Which is to say, even though everybody loves a bright blast of color, sometimes a few shades of gray can express just as much, but with a quieter, subtle touch.
