some zentai wearers are not satisfied with wearing only one zentai suit nowadays, they want to put more on. so some of them begin to try the idea out. taking the man in the picture as example, he is wearing five zentai suits on, one is the spiderman costume, one is the purple lycra zentai suit, green zentai suit, black zentai suit and the white zentai suit. there is no need to say that this is really cool. and i am sure that people couldn't know the exactly feeling until they try.
as for the cool thing, many people would love to have a try, so i guess that some zentai wearers will give it a try soon. however, you should pay more attention on your safty since zentai will cover you fully, anyway, for our humanbeings, safty is the first thing, so when you are going to try to wear multi-layers of zentai, you'd better have someone at your side.
