This skin takes advantage of the selective clothing in skin customization to overlay an emoji morph suit over your regular skin.

The skin under the emoji suit is a very basic skin that could be easily changed by layering it on top of your desired skin using NovaSkin or NeedCoolShoes. So you could easily put this emoji suit on whatever skin you want.

Personally, I enjoy not wearing the emoji suit most of the time when I play, and then putting it on when my friends turn their back.
