Kylie Jenner leaves nothing to the imagination

I saw this picture up on Instagram this weekend. My first thought was, why would you take this type of selfie, is it the whole 'how ever many likes you get will validate me' kinda of idea? In saying that, the pic has over 2-million likes!

Is this an overshare or an example of self expression?

If you had a body like this, would you snap and post it online?
