Everyone wore a suit, and a hat back then. Every guy in the world. They looked 'way cool' too. Our current "Era of Informality" which evolved from the 1950's to today. This will be one day seen as a Bizzaro period. Much as we now view everything people wore in the 70's.
Btw,...has anyone written a book on how 1970's fashion happened?
If they have did they name names, and will there be trials?!
