Sure, I spend a 16 months in Chicago and now you come up with a post? Seriously, I did the same thing, wore shorts, speedo, etc. to work out in, depending on my regimen that day, then showered and put on a kilt to head out and go to the office. I NEVER had a bad comment. Some polite questions about playing the pipes, why a kilt today, etc., but never anything derogatory. And like you I was extremely leery and concerned that I would get those kind of comments. Search my older posts and I am sure I shared some experiences.
