Is nudity the best form of Art?

Okay, this is really off the usual topics I blog about. I was looking at some pics when it stuck me that the best model is the one that is barely dressed. Interestingly, the same goes for a successful fashion show (apart from the fact that the dresses have to be really loud).

I am probably not the best judge of art because the rationale about nudity being the best form never striked me (and I am open to hear further on this).

Off Note:
For all the sex quotient that marketing brings in, it definitely qualifies as an art.
