So with that in mind, I am trying to strategize this, to see the most effective way to go about with without taking forever to do.
I think rotoscoping would be the easiest way.
You would film yourself doing the dance (placing your camera at a certain distance to get your whole body with the least lens distortion as possible, standing in front of a neutral background), or somebody else doing the dance, then you follow that as a guide.
There are some tutorials out there, like this one:
https://www.youtube.com/watch?v=-jvXJs97bPoIf instead you wanna do everything by hand, then you could start with a stick figure. Do the whole animation just with sticks and circles (for the hands and head, maybe joints like the shoulders and the elbows), and then after the animation is done you would start adding flat shapes on top of that to flesh your character out. Forget adding finer details at this point, leave that for last. Work with just the bigger shapes. Head, torso, arms and legs.
You could try and separate the limbs in different layers to more easily follow each of their movements. Paint them each in a different color, ignore your actual colors for now. Just be sure to be able to see each limb and the torso separately.
After that is done, then you would go and add another level of detail on top, painting with your actual palette, refining the shapes of the character. And then you could add the chain and fringes and whatnot. But as Sein said, that's gonna take a lot of work... Not just because it will be hard to draw each frame, but because they would move with a little delay in relation to the body. That's called secondary action.
I'm sure you can find animation tutorials about that too.
Btw, if you right click the imgur picture and copy the URL, you can post it here directly like this:
Alternatively, you can click the "..." button on the top right corner of the image and then "Get share links", then copying the "BBCode (Forums)" link.
(dunno how that works if you're on a phone or tablet.)
