I remember a time when people found it necessary to wear "real" clothes when they were out and about. Whether they were running errands, grocery shopping or walking the dog. Jeans and a decent top were in.
This all changed at some point and I can't actually place my finger on when. All I know is I woke up one day, took off for the airport and everyone was in lounge wear. I understand wanting to be comfortable, but I still enjoy when people take pride in their appearance and make an effort. That seems to be a thing of the past.
