Live and let live.
I used to think it was something I'd never do, until I had a pipe burst in my studio apartment at 6 am and the pajamas I was wearing were the only dry clothes I had. Eventually, I had to clear out so the plumber and clean up guys could do their thing. I picked up my friend who wore pajamas in solidarity, and we eventually got food at a restaurant (I asked if we could be seated wearing pajamas, first). It was the end of a very difficult week, and very surreal to be so physically comfortable and emotionally uncomfortable at the same time, but I think being in pajamas weirdly helped the situation.
