Sometimes it's the simplest of questions to which man seeks the answer.  MA has one about matching socks with grey suits.

Q:  Black w/ black suits, blue w/blue suits, what color do you wear with charcoal suits?

Thanks,

MA

A:  MA - there is but one answer.  And that answer is grey.  I have a dark charcoal suit in the wintertime and a med-weight light grey suit for year 'round.  Brooks Brothers has over-the-calf socks in a solid medium grey that go with both deeper and lighter colors.  Grab a few pair of the same styles in case you lose a sock along the way - which I have done.   You can also wear grey socks with some bold colors in them, such as argyles or stripes, if you're so bold.
