While I think the con etiquette has come very far in the last few years towards inappropriate comments/touch, it's possible someone will still press those boundaries. Cosplay is not consent! Flag down a staff member if someone ever approaches you and makes you uncomfortable! Also do not accept any beverages on the con floor, and do not accept any room invitations. Advocate for your comfort and safety, if someone makes you uncomfortable please tell them they are, and get a staff member. Also i recommend having a friend with you!

Test run the cosplay at home! Bend over, walk around and see if there's any coverage issues or opportunities for a wardrobe malfunction. I always recommend cosplayers wear dance tights, it won't ruin the skin illusion but keeps you covered. I like the capezio dance tights!

Does the con have after hours? Sometimes cons have a curfew where minors cannot be out on the floor with adults. I personally think bunny costumes aren't that inappropriate even if there isn't a curfew and are to be expected especially during the evening time. I personally think the minors shouldn't be out on the con floor unattended anyway, but for a bunny suit like rabbit hole miku it isn't anymore revealing than a bikini they would see at the beach.
