Our community no longer has a dress code in the Resident Handbook. We have moved on from coats and ties 15 years ago to no comment on clothing. The newer residents do wear shorts in the dining rooms which was not allowed when we moved in 9 years ago. Most men wear slacks and a polo shirt or a collared shirt. T-shirts with designs have been more common with new residents.
Five years ago, the Residents' Council tried to come up with a dress code but dining services management said they were in the hospitality business not in the enforcement business. Many of the "old guard" that clung to the standards of dress from 20 years pushed back a bit but that passed.
Women seem to know that shorts aren't a good look so capri pants are very common in the summer. Flip flops were a "no-no" but now women wear expensive sandals with a toe thong that looks like a flip flop but is not the pool or beach type. How do you tell someone that their $200 sandals are not suitable.
Life has become more informal and it is reflected in our dining rooms and on cruise ships. Family members do come in with more informal dress and we see an occasional ball cap backwards. Sometimes the resident will say something and they take it off but others are so glad to see their family members they let it go.
The pandemic caused more informal life including no tablecloths in the restaurant venues.
