Something I did years ago was start wearing hiking socks as dress socks. I get the dark black/blue ones so they look just like dress socks and if you shop around enough are not any more expensive. I bought a bunch of the three packs at sams club back in 2003 and still have a couple that haven't been worn. The colors that don't work for dress socks I don't have any grey pants but three pair of grey socks) I put in my BOB at home.
