1. Ask permission, not forgiveness–and keep your eyes up
Want to take a picture of a cosplayer? Ask, and ask politely, rather than snapping the picture covertly. If they say no, then accept that the answer is no–don’t try to sneak the shot in anyway. Under no circumstances should you take a picture that focuses on a single part of a cosplayer’s–or anyone else’s–body, rather than the whole person. And if you’re posing for a picture, getting something signed, or asking a question at a panel, keep your eyes on the camera, or the face of the person you’re talking to.
2. Don’t be judgmental
If you’re an experienced cosplayer, you might run into people whose costumes you don’t consider up to par. Maybe they don’t have the right prop, or the right wig. Remember, you don’t know what that person went through in making that costume. Maybe they ordered a prop or a wig but it didn’t come in time. Maybe they don’t have the money to buy the best materials. Don’t be judgmental.
3. Celebrate, don’t compete
If someone shows up in the same costume as you, you might get a little annoyed. However, that person is just offering a different perspective on a character you love. So for cosplayers who run into another version of themselves, it may be more fun to offer a high-five than a critical eye.
4. Don’t Touch
I don’t care how big a fan you are of the character, don’t run up and just grab someone. There are real people underneath the character and costume. Cosplayers don’t want to be pawed at. If you want a hug or a pose with your arm around them, politely ask their permission first.
5. Don’t Creep
Don’t monopolize the guest artists’ time. Others want to have a meaningful experience, too. Have yours and then move on! Also, remember, don’t touch! Hanging around because you have crush on them is flat out creepy. Once again, move on and, if feel you must, just admire them from afar.
If you’re cosplay character carries a weapon, make sure it doesn’t violate convention rules. More importantly, though, you should be aware of where you are in relation to other people when you brandish it or swing it around. If you and a fellow cosplayer stage a battle, make sure it’s not in a crowded area of the convention hall. Use your common sense and no one will get hurt!
Make sure you drink plenty of water throughout the day. Especially, if you think you have the possibility of getting overheated in your costume. I understand your level of commitment to your character, but passing out in the middle of the convention does nothing for your character. Also, make sure you eat because an empty stomach makes people irritable and snappy. There are just too many people packed into an event center for you to come down with a case of “hangry”!
