Your saying you'll wear sweats to keep warm reminded me of something.
When I first got out of college, I moved into this apartment to share w/ this girl Dianna who was already living there. Was in South Fla.
I'd come come at 5:30pm in August, and she'd be sitting there with the air turned down to 65, wearing sweat pants, sweat sox and a warm up jacket...in the winter I'd walk in and it would be hot as hell in there, and she'd be wearing shorts and a halter top.
I'd ask her why she was wearing one or the other, and she'd say "I'm cold" or "I'm hot". When I suggested she either turn the air warmer, or the heat down, it was like this was a really amazing idea.
