In Denmark most people (or women at least) wear a blanket when staying home on a cold day. In England everybody wears a dressing gown.
This is so uncommon in Denmark that when I video Skyped with my mother, her first question was, "What is that you're wearing?"
"A dressing gown"
"Why?"
What about slankets (sleeved blankets)? They're warm and fleecey and you can sit down tucked up under them, don't get cold arms if you need to reach for anything/while reading - but they're a bit narrow, so when you get up, you get a chilly back. Unless you wear a dressing gown and a slanket! If you're short, you can also have your feet wrapped up in the slanket whilst walking :-D

Never thought to tie it up. No wonder your culture is declining.
