I'm not comfortable at Arisia. I think I would be better about it if it were not coincidentally Claustrophobiacon (awkward hotel, crowded, narrow halls), but the one time I attended in its previous location I was still not comfortable with many of the costumes. It was riiiight on the border of bystander consent, and I don't like being that close to the border.

(Some dealers' materials are similarly borderliney, although that was my own fault -- individual dealers are in individual rooms, so I could just have not walked into that one.)
