Plenty of real men live their lives not worrying or thinking about what other men are wearing or caring what others think, and they are better men for it. Many other examples of men had insecurity and other issues who compensated by trying to be fashion plates, but they were broken men.
Do you really believe that you don't care what anyone thinks about you? I find that most people who say that internally feel quite the opposite. Otherwise, what would be the need to tell everyone that you don't care?
Why comment on this thread if you are so above it?
