What is this?

Another Nude gals? Naahh...watch it closely, it's printed on the fabric...it's not an X- Ray...it's only an image printed on the skirt or shirt.... I've found this news on Japanese gals, harajuku models....I'm wondering would u ever wear those shirts? It's quite embarassing when ppl looking at me.. : (
I never imagine wearing those skirts to mall etc... I've seen it once in Bali, Indonesia, Do u have it in ur country?
