We had a pretty big change with JFK, who made hats seem stodgy. What's next to fall? Jackets? Ties?
Ties and suits are quite literally costumes, costumes for theater.
A good jacket can make a person look good but modern necties...i dunno, they just look silly on an everyday basis. I'd much like to see the return of flowing Cravats. In the film Nixon you can see Anthony Hopkin's lead charachter wear one for Nixon's wedding.
