Hats, ties vanishing, sloppiness becoming a standard
It used to be that hats were regular for all sorts of working folks including security guards, railway staff, bus drivers. Ties were a a standard thing and bad enough that odd MP's turn up without them but on tv politicians in discussion doing the same. Makes them look untidy and daft. Beards everywhere another thing and my mother used to get annoyed at that rushing into as she felt it showed them as not being very bright and hiding behind them as if showed maturity!
