I would love to go to a resort like Cape d'Agde and spend a few weeks or a couple of months never wearing anything but a smile.You might do better at Euronat on the west coast of France where there are not the sleazy overtones of Agde.
Another option might be the Canary Islands. Someone on another board moved there after he retired. He found nudity to be widely accepted, including some places that were not officially clothing optional, even some shops and outdoor cafes and taverns.
He also found that in most places that didn't permit full nudity, a light wrap would suffice, and on the rare occasions that he had to be "properlyP dressed, he wore a kilt.
The last time he posted, he only had one pair each of shorts and slacks and hadn't worn either in over 2 years.
