It's interesting how different generations change. But I'm interested why it's important? What do the "standards" actually mean...? I can see the need for clean , appropriate clothes outside but in your own home, what is the problem to wearing pjs at 10am?
My own mum wouldnt have lounged around in pjs or dressing gown, although she did make a cup of tea in the morning and I remember she once ran into the garden in her nightdress to chase a squirrel who was digging up bulbs!
She always dressed smartly, I don't think I even saw her wear trousers til I was well into my teens, and she never owned a pair of jeans. She wouldn't leave the house without make up on and always styled her hair woth a hot brush. She dressed up for parents evenings or travelling on a train.
I wander about in PJs and dressing gown occassionally at weekends, probably up until about noon, at the latest. I often do parkrun and a Sunday run though, so it's not every weekend. I might play cards/board games or chess with DH or kids, or do some chores or cleaning before showering and getting dressed.
I rarely wear make up unless I'm going out for the evening and mostly dress casually. I sometimes go out with wet hair if I haven't had time to fully dry it (I didn't realise this was frowned upon until I joined MN) In person parents evenings were often straight after work so would turn up in jeans, trainers and hoodie.
