If I’m going out, I change from cosy indoor clothing to tidier clothing so that I don’t look like I’m wandering around in public in my pyjamas, so I guess I’m fitting to a societal expectation, and thus dressing for other people in that regard.

That said, I wouldn’t want to sully my indoor clothing with the outdoors anyway, and I don’t like going out as a rule, so I think I prefer to be dressed for myself.
