At home I just sleep in boxers and walk around in shorts and a t shirt but obviously uni isn't home. So do you think I should get some pj's for uni.
(might even wear them to the shops and lectures)
I wear pj's all the time to go to sleep in at home. (Obviously, when not in bed, I don't wear PJs, I wear normal clothes.) Though I wouldn't recommend wearing PJs whilst going to the shops, and definitely not in lectures. (During my 3 years as a university student I have never seen anyone is PJs at university.)
