Be anoynmous is good

When all the things are the same, a brght color is always the main eyes-chatching. like the orange man. he is in a orange spandex zentai suit that covers him fully. he is all orange now. so compared with other people, he is not going to be ignored for sure.
Zentai allows people to run around anonymously and get instant attentions from others. it's ok to see through, breath through and even drink through. the normal daily life stuff is totally not a problem for the zentai wearers. also the color of zentai is various, almost every color is available, could be used for the colorful events.
People don't know who you are when covered in zentai, but they still would love to chat and make friends with you. many people like to judge a person from the looking nowadays, it's kinda unfair to all. so maybe fully covered is good.
