I haven't owned a pair of pyjamas since I was a child!
Seriously, I spent two years of my childhood either being ill or convalesing and grew to hate nightclothes and dressing-gowns, as once I was well enough to be allowed out of bed, my mother insisted I didn't dress, so I could get into bed again fast when she could see I was getting tired.
So I only wear nightclothes when I am ill, or sharing sleeping accomodation with strangers or young children of friends or family when I would not feel comfortable in my usual night attire = my birthday suit.
I get up, wash, dress, drink coffee and listen to the news, unless I get up as I did yesterday and realise that a migraine is luring and go back to bed again.
