Actual belly dancer doing an actual belly dance. The first one is the example I find most likely, but this actually an entire playlist of 99 different belly dances, so ... bon appetit.
In some of the preceding videos, you will note that I stated that the dances being seen are not belly dances. That's true, strictly speaking, even though all of them use some elements of belly dance. Generally, the nakeder the dancers are, the less actual belly dancing is going on. It's a rule of thumb, I have seen completely naked women doing a dance that is at least close to belly dancing. For example, some of the dancers in the "Actual Naked Belly Dancers" video are doing actual hip drops and shimmies, if not particularly well.
I picked the video above, not because it's the best belly dance I've ever seen from an aesthetic point of view, but because it illustrates the sort of moves that constitute belly dance: hip drops, shimmies, shoulder rolls, etc., along with the expressive use of the hands (though I've seen much more effective use of hands by other dancers).
Princess Jasmine's belly dancing is a lot faster-paced than many other belly dancers but that's just a function of the song she's selected. Here's a belly dancer whose pacing is slower much of the time, but there's the same fine control of her body as she moves, especially the hips, stomach and torso. (Also some very nice hand gestures. Embedding is not allowed on this video, but you can see it on this link.
Here's a video that will give you some glimpse of how belly dancing can work when The Sexy is interjected into it: a gorgeous dancer with a very nice set of silicone implants dresses in a notably scantier costume than the others. In the last third of the dance she shows some very nice hip and torso moves. I imagine that integrated with a naked exotic dancer's deliberately sexy moves and I go "Mmmmmmmm."
Some skilled dancer may very well have already done this, but ... haven't seen it yet.
Now when you see a stripper or exotic dancer just rolling her hips and calling it belly dance, you'll know the difference. Public service accomplished!
