I think a day will come when most understand that the naked form is nothing to hide. While clothing is rather practical for cold climates I could see taking a tropical vacation and seeing many naked people without it being terribly strange. The problem with it today (mostly in America) is that we are so oversexualized so if you see a woman naked rather than thinking "there is a woman" all one would think is "OMG TITTIES". Such an immature mindset will not allow for nudism to be a popular fashion for quite some time.
