I like how Ancien Maestro expressed it about making himself comfortable while allowing others to be comfortable, too.

What you personally wear you didn't say, but I do believe we all contribute to the group experience of flying and so we need to bear that in mind choosing what to wear and how to act. If you were badly dressed, staring at you would be bad manners on my part.

It is so easy to dress comfortably yet modestly, even when it is hot. Board or Bermuda shorts instead of short shorts, a tee instead of a scooped out tank.

Saw a sign today at the public library saying you must be fully dressed and not negligent in hygiene to enter. A higher standard than is enforced by the airlines, it would seem.
