I think that shoes should be comfortable, as for other parts of the costume, there are no specific rules, for example, that year I wore a silicone mask https://www.themasker.com/ instead of makeup.
Hello, awesome cosplay character, but I want all of these to be some kind of scarier character. Even for this I plan to buy a mask https://www.themasker.com/
I like more complicated characters. For example, different zombies for them are very cool to buy different realistic silicone masks https://www.themasker.com/ , then the photos are not really beautiful.
