So you're okay with casual, just not less casual than you choose to wear?

I don't leave the house in pajamas, but I see no problem with wearing them outside on occasion. They certainly cover one better than some clothes that are perfectly acceptable as "outside" clothes.

I'm not trying to give you a hard time, Madds, but you're no different than uptight brahmins in the 50's being scandalized by people wearing "dungarees".
