Men's fashion advice please?

[Epiphainein]

Do you buy your man (or men in your family) black socks or colourful socks to wear with a suit/slacks for work?

All black, and identical if possible.

Nothing to do with fashion, and everything to do with easily finding two similar socks when I'm getting ready. Plus, if one sock turns religious, its partner can still be used.

They buy their own, AFAIK.

My husbands suits are grey or dark blue so he wears grey or navy socks and would only wear black socks with a black suit/trousers.
