Get yourself a nice brown leather belt and a nice braided belt to switch it up every once in awhile.
Get yourself some nice leather chukka shoes (not boots). Get some that the more you beat the shyt out of them the better they look.
I stopped buying ties once I moved to the West Coast because everyone thinks they are weird out here. But layer up with any of the shyt above and throw in a tie and your pretty much good to go wherever.
