Buy 3 adult onesies. Wear two at a time, you hardly ever need to wash the outer-most onesie. Alternate the other onesies as you wash them. Sleep in the inner onesie. You want your onesies to have feet, at least that's my preference. When I was a student in Edinburgh, I lived in an old tenement with super drafty windows and super high ceilings. Trying to heat the place was pointless. I gave up and just wore two onesies whenever I was inside. In the winter I used to wake up and see my breath, I'm not sure how cold it got, but definitely colder than 17. I think that was the indoor temperature on a cold summer day.
