I have no idea why many online game companies like to use “zentai”as game costumes.Maybe “zentai” is widely used in these famous online & PC Japanese games.Yes,this kind of tight clothing seems more easily to be designed and the characters will look very sexy,especially for these female characters.But compared to traditional “zentai”,these game costumes look much more complicated. So is it a problem for you to cosplay as a game character?No,it is very easy because the costume can be bought easily.
Let me take D.va from overwatch as an example.This hot character looks very beautiful and sexy and so many cosplayers(maybe most of them love this game too) would like to use this idea for next event.
Basically the D.va zentai will be made from spandex/lycra too and the only difference is that the fabrics need to be made with the patterns and then the whole suit will look authentic enough.You may commission the amazing zentai company “zentaizone” to custom make it for you and what you need to do is that send them the pics.They will design and create the pattern before producing.Then they will print the patterns on their fabrics to make this zentai(that will be almost same as the one in the game) for you.
In fact no matter what kind of zentai suits you want,they can custom make for you as long as you provide them with quality pictures.
