People about Cosplay...
There’s a few things – one is that you you’re going to get asked for pictures, especially if you cosplay a popular character.
For conventions, make sure that you have a way of carrying essentials on you, even if your costume doesn’t have pockets. Perhaps make a simple bag to match your costume (same color as your outfit, or decorated with a suitable design, an example being a Jedi costume with the Jedi order symbol).
Wear your costume around before the convention, to make sure that you can move around in it, or that things don’t start slipping/pinching/falling apart after a little while. At home, there’s lots of time to make adjustments and fixes.
Don’t worry if you’re not as good as some of the veteran or professional cosplayers out there. Those cosplayers started somewhere too, and with practice, you too will eventually get good.
Costuming has been around a long time: we find artifacts from tens of thousands of years ago where they were used to portray a being or spirit. Often those who played the parts in costume were held in high regard.
A little time with kids or a parade group reminds us all how much fun people have – let alone when there is a formal play being staged. Costuming is fun; it’s fun for people to pretend, but it should be understood by all that it’s to be pretend. Problems come when the “role” gets mixed up with one’s being; the role defines the person instead of the person defining the role.
As Jack Nicholson famously said to Michael Keaton as they were suiting up for their roles in Batman (1989): “Time to let the costumes do the acting.”
When the role is more than the person, that causes psych problems.
Costume play is very powerful tool. Any role play, with or without costume, allows a person to express things with much less risk and responsibility. Through this self exploration proceeds unimpeded, and new behaviors are tested to see if they will be useful.
Constructively used, this allows becoming more oneself and testing of one’s environment and abilities. I allows a person to test revealing things about themselves and see if it meets with rejection, and extend their comfort zones. It allows testing of fears, e.g., permitting a shy person to try being outgoing to see how well it works for them.
On the other hand, a costume, role or disguise also permits a person to enact their worst and most damaging behaviors anonymously. It is far easier to behave badly if one has a costume or role which hides the identity of the person both literally and figuratively.
