Should I buy a bathrobe?

My friend over the weekend was bragging about how he has the comfiest bathrobe that he loves and that I should get one too. Here's the thing, even though I love the comfort of a bathrobe, I can't think of when I would ever use it. I typically wear sweats when I'm working / hanging out around my apartment.

So here's my question: do you have a bathrobe? Do you actually use it? Is it worth having?
