I tried on a pair of Mephisto walking shoes once. They were very comfortable and I took a closer look. That was as far as it got. There on the side of the shoe was a label with the maker's name. On the outside of the shoe, mind you. Just look on the heel on the right side of the photo.
So let's get one thing straight right off the bat. As far as I'm concerned, external labels of the sort found on certain brands of shoes and hats are not venial sins. They're mortal. Unforgiveable, you'll-never-lunch-at-the-Four-Seasons-again class sins. The venial sort is the alligator or polo player logo on polo shirt type, like the one on Ralph Lauren's shirt in the photo below.
Now, in tolerating these I'm probably being generous, as those little icons were the first step down the road to the man-as-walking-billboard wear we see around us today. And I need to be clear that I don't possess a single one of those logo'd shirts so I hold the moral high high ground in any debate. But I consider them a minor sin. After all, if I took them more seriously I'd never find anyone to play golf with.
Don't even get me started on those neckties with the maker's logo woven in.
