Oh dear, I too love my jammies but I must admit I was a bit shocked recently. Dropped my son off to Halls at his uni only to be greeted in the corridor by a girl in her pjs and hoddie, she was wandering about chatting to people in the kitchen area (it was about 2.00pm ish). Thought to myself 'she's really made herself at home here' (she could have only been there a day or two). Later on that day I went to put my kid's food in the fridge (in the communal kitchen) and lo and behold another one there, chatting and cooking away in pj bottoms and a hoodie too.
Must be the in thing. I didn't like it.
Call me old fashioned, just like I did not like getting a loaf of bread a couple of weeks ago from my local bakers and the grown up man in front of me was wearing Marvel Adventure designed pj bottoms with a scruffy jacket - eugh!
