Loved your post. A smile is appropriate anywhere, any time!
It is not just young people who no longer want to follow formal wear specifics. I'm well into my 2nd half century. Done plenty of true formal wear for one lifetime. I still dress up, but not like when I was younger.
Formal wear trivia...the "no white after labor day" also used to apply to tuxedo dinner jackets. Men wore black from Labor Day until Easter, then switched to white dinner jackets. I actually enjoyed one aspect of all that. When Easter came, the white patent leather shoes came out of hiding and that meant that winter was over...even if we got more snow and had to go back to winter shoes and clothes.
