I love to wear PJ's all day sometimes, especially when i'm not doing anything. We wear PJ's for bed anyway because they're extremely comfy and easy to sleep in.... so why not wear the most comfiest clothing you own? If i could get away with wearing them when i go out anywhere i would!
I have seen a couple woman in my time wearing a dressing gown going around the supermarket. Bless them lol I wish i had the guts!
PJ's are the best clothing ever. Nothing wrong with a pajama day.
