I'm with fbgbill on the LLBean mocs. I wear out a pair every 2-3 years because they are always on my feet (indoors). And I do wear a bathrobe over my normal shirt and pants. And my hand does usually have a glass of bourbon on the rocks. So if you can picture an 84yo sitting in a chair wrapped in a navy Terry LL Bean robe and slippers, sipping a Makers Mark on the rocks, you've got an up-to-date picture to contemplate. (And yes, I do often sit off to one side of the room.)
