Upon looking at things again.. you're right, that was added like at the last second XD
No wonder it doesn't work!
Would it be possible during Halloween week to allow male characters to wear their bought shirtless costumes in all buildings?
I bought the Barbarian outfit. While I was allowed to wear it to the Halloween party itself, I wasn't allowed to wear it to class or in any other buildings since the costume doesn't come with a shirt. Seems like a loosening of the rules would be okay for Halloween week.
