Here is a dynamic belly dancer outfit at 3D Commune.

It doesn't show up when you search. But if you click on "what's new" for the store, it's in the top row on the second page.

Actually, that is the same outfit as found here:

The reason it's a static prop is because it's dynamic clothing that you need to work with in the cloth room.

If you do not know how to use the cloth room, here are some links to some tutorials that will help you:

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
