Ok, so as I'm coming from a country where cosplaying is far from popular or common...sadly it's mostly due to lack of bigger comic/movie/nerdy style events, the whole logistics of it kind of confuse me.
Do people come in costumes to the event, drive in a car or ride in public transport and such, or do they change into costume when they get there? If they change on spot, what do they do with their "regular" clothes? Do they go to stands to get their stuff signed or to buy stuff, or just walk around taking pictures with other visiotrs? Are they paid or get free tickets, do you need a license/permission/registration or is it just a regular visitor with a costume?
...or am I just overcomplicating things and it's on a person to person basis?
