Staying home? Old pants (shorts in hot weather) and whatever short-sleeve (summer)/long-sleeve (winter) shirt is next in rotation.

Going out? Pants that don't show fraying on the cuffs (if I just clipped them they don't show) or cargo shorts. Columbia "fishing" shirts with 4 pockets + pen holder and sleeves that roll up in warm weather.

I have "nice clothes" for church or funerals. Or parties, I suppose, but we never get invited to any, so there's that.
