Why yes, I do accessorize with belts/buckles.
I have the Addidas trophy buckle that I use with a black smooth belt (for black shoes) and a white perforated leather (for use with white shoes). I also have 3 trophy buckles; red, royal blue, and silver, which I alternate to match my shirts and hats. As an FYI, I have written to our friend Scott Cameron and requested that he add a stainless steel buckle to his Custom Shop offerings. Think of that one my friends!
Since no one brought it up, it must be plainly stated.... a belt should match the shoes in primary color. If you wear white shoes, the belt must be white (are you listening TW?). Anyone with style understands this fact. If you have a black / white combo on the shoe, it's OK to have the black belt, but only if the shoe has more black... It's the same with socks... they match the shoes.
Here endeth the lesson for today!
