A couple of questions - out of pure curiosity - to people who spend "90% of their time at home in their pyjamas". Do you wear underwear underneath? Also, do you have a separate pair of pyjamas for sleeping in, or do you sleep in the same ones you've spent the day walking around in?
I actually do spend most of the time I'm home in pyjamas. But that's because I'm not home very often, so I'm mostly home when I'm sleeping...
And I don't spend the day walking around with them.
But as I may have mentioned above, I was wearing a dressing gown when some family members came over for brunch a few weeks ago.
DD was super fussy and I just didn't have time to get dressed. But, seeing as I shower in the evening, I do have a cat's bath every morning when I brush my teeth, do my hair etc... I remember doing that when the door rang. So I simply put my pyjama back on, grabbed the dressing gown and went downstairs.
As to answer your question... I don't wear a bra, but that is not visible when I'm wearing a dressing gown. My breasts aren't big enough 😅
And I can't remember whether I wore knickers. But seeing as I did wear thick flannel bottoms and a dressing gown that covered the whole area anyway... who cares?
I personally would not wear pyjamas at 4pm, especially not if we invited somebody for a Christmas party or something similar. But I wouldn't mind if somebody did!
