Should all else fail, the Hay tartan in a comberbun, tasteful, nice with black.

Now, in my old school days, I would have worn light slacks with button tabs on the legs, shorts to slacks n seconds. But, than again that is why I wa always on the superintendants hit list. Yes, not the principal, the superintendant. I try to make my impressions at the top LOL

Best of luck, and best wishes...from a Boyd!
