My old man always said there is no such thing as “over dressed”. Although on a normal day he would often mix checked and plaids (”Hey - they both have red in them”).
But for an event, dinner out, etc. it was always a suit and tie. I have old photos from the 40’s and 50’s and mom and dad’s travel attire was wonderful and dressy.
I have one photo of my mom with my dad’s father around a camp fire. Mom took my dad’s place at deer camp when he was in WWII. Grandpa has a suit, tie and a Fedora on in what appears to be a dreary wet day out in the woods.
I don't think those days are ever coming back.
Even when I go to a high-end steakhouse these days, I'm seeing people in cargo shorts, t-shirts, and sandals.
I remember that in the 1950s and the 1960s people dressed up to go shopping and when they traveled. Never saw my father leave for the airport without a tie.
