I'm just surprised that the men themselves don't see it, although Andy (or Kim!) obviously know what's right, but, as you say anything goes now, and that includes not wearing ties with shirts, which to me just makes them look scruffy, yet even TV presenters and interviewers often don't wear ties.
I stopped wearing ties when I stopped working in an office. It wasn't compulsory then, but I didn't feel right without one. It put me in working mode. Don't wear them to any social events except funerals and weddings now.
