Not so long ago a decent man would at least wear a black tie tuxedo every single night. Maybe blue collar folks did not. The Upper Class. Middle Middle. Lower Middle. Upper Middle Class. All would. This trend has died somewhere in The Middle Of The 1940s or The 1950s or The 1960s. Why do you guys think this has happened? What do The Decent European Male Aristocrats and European Male Royals and The New England Men Of The Upper Class Wear Today As Evening Wear?
