I'm dreaming about swimsuit that would be transparent to ultra-violet rays but impenetrable visually. In this swimsuit anyone can become sunburnt without any trace of clothes, I mean without white shapes of a swimsuit on your body.
There are many materials to fulfill this. The simplest one is to use such gauze material (with very small pores!!!) that would refract sun rays, so that they eventually reach the body… but because of the gauze material the body is invisible.

What do you think abt the way to get perfect tan without much efforts and besides- naturally?

Placet?
