i would add cosplayers to the list as an optional bonus to take into account XD
One of my Oc`s from my comic is a parody of the "sexy female villain" and heels would fit the archetype, but i didnt gave her heels just in case someone gets to cosplay her. (so instead got her some fancy boots)
I researched about the negative effects of wearing heels for an university project, and after reading how harmful they are, decided to take that into account.
and even if it`s just for a day in a comic-con or something, at least it may be more comfortable to them.
Is not like i will shun people who give their character`s heels or anything. I would even add them for the sake of parody
