No matter how in character you are trying to be, DO NOT purposefully be loud or touchy around people. This includes barreling into people as you run through a crowd.

Also do not be overtly sexual in what you say around people you don’t know. I have a friend who was cosplay ing as Haruhi from Ouran. She is a survivor of rape. A Hikaru and Karu cosplayer approached her and started making very sexual remarks that they thought were just being playful, but they were very triggering to her and she ended up having to go back to the hotel room for a few hours.

Just be mindful of disabled cosplayers. There are more of us than you think, and we just want to be able to enjoy a convention without being nervous of all these things happening.
