I still don't understand this. I just stick my pajamas under my clothes, you can never go wrong with that method plus it's comfy as hell.Nahh I just can't dress well for it lol. I'd even suffer the same (or worse since it's apparently way colder over there) if I was in Minnesota. Uk winters are really cold but not as much snow
Hell if I'm going to the store I just slap on my clothes over my pajamas, no need to change and I'm comfy the whole time.
