I started wearing a bathrobe at home throughout the day and it's a godsend for colder seasons.

Especially in bed where I'm prone to move often while sleeping. I usually wake up partly frozen because my fatass manages to unfold my clothes and expose my lower back quite easily, and it doesn't happen when the whole bathrobe covers that body part quite well.

Also cutting down on electricity since I'm not heating up the room as much as I used to. Would recommend.
