As someone who has been going to nude beaches for almost 20 years, I definitely have had experience with this.
A few years ago, it was a really crowded summer day at Gunnison Beach (in NJ). I remember that a very young couple (early 20's) was walking down the beach from the clothed area. I don't remember the guy, but the girl was kind of a gorgeous hippie-looking girl. Very natural, wavy hair past her shoulders. Black sleeveless t-shirt and cutoff denim daisy duke shorts. Very fair skin. Cute face. A little like Juliette Lewis (Cape Fear).
They were shyly smiling at each other as they walked down the beach - looking at each other like "Can you believe this?" I kind of lost track of them for a while because I was just going down to the water to cool off. However, a while later, I happened to very fortunately catch sight of them as they were walking back. This time, they were buck naked. She had a superb body. Breasts like big hanging fruit, but firm, and large nipples. Big dark bush. Athletic, slim body with fair skin and no tanlines. They were holding their clothes in their hands. It was really awesome to see.
