Two thoughts on this thread.
(1) It reminds me of cruise threads 15-20 years ago about dressing for formal nights on cruise ships. One school of thought was that it was an elegant tradition worth keeping, and the other that people who paid should wear whatever they wanted where ever they wanted. I think most ships have devolved to “please don’t wear shorts and flip flops but we’ll let you in regardless.”
I myself like dressing up a little for Thanksgiving and seders, but I don’t play football.
(2) Many years ago, we were hosting Thanksgiving for my mother and my brother and family.
Between cleaning and cooking I didn’t have time to touch up my roots (I was doing it myself in those days) or getting it trimmed. I did wash and dry my hair! The next morning, my mother called and wanted to gift me a trip to her hairdresser as a Chanukah present. I could only imagine the conversation in the car on their half hour drive home. I declined, and only partially because all I ever heard from my mother about her salon was complaints.
