To think that people who wear PJs outside haven't actually slept in them?

[Utterbunkum]

I have seen much discussion about the public wearing of PJs and it has made me curious. I haven't worn PJs in bed apart from on very cold nights and when in someone else's house in case I need the loo in the night ( and then it's a nightshirt) since I was a child. Are people really actually sleeping in the sort of night attire some report seeing people wearing in Tesco's? I can't imagine going to bed with my DH in a big, fleecy onesie or fleece PJs.
Do a lot of people wear PJs in bed? Am I unusual?
I rather thought the modern PJ wearers were having 'duvet' days and didn't change to shop, not that they'd slept in it. I thought PJs were just the new casual, loaf around the house wear, but some posters definitely seem to think people actually sleep in them. Do they?

Actually they relatively are, pyjamas is an Indian word and came from colonial times along with juggernaut and shampoo. Night shirts prior I think....

There was a lady who lived down my road, think she has passed away as house was sold.

She always wore the same PJs every single day I saw her plus dressing gown which was filthy.

I have worn PJs when I have bought the odd thing at a supermarket, but they were underneath a hoodie and some joggers

I think that generally going out in pyjamas is perceived as being pretty scummy around where I live. I've never really considered that people might have changed into fresh pyjamas to go to the shop. Why wouldn't you just put clothes on for the day.
