The big challenge is a suit not worn with a tie. To me, it's a very odd look. David Cameron and many of our British politicians have adopted this look. I think it is challenging for men to look chic in casual clothing. Most people just want to wear T-shirts and baggy shorts and don't really care, whereas in the old days people used to really dress well in their leisure time. The suit has become a victim of that. day to dress in an appropriate way.
