if you really want to know then:
there are many other ways to do it but this is the one I came up with some time ago, I might as well update it to something more practical later. start setting the mother node on the place where the hoodie should move from, this is more certainly the back.
Start an invisible node on that mother node, this children node will be the node used to move the hoodie, make sure it’s stretchy with smart stretch on, you’ll add a curved set of rounded nodes starting from that node, these should have a curved shape since they are sort of the sleeve of the hood, make sure it’s curved enough so that when you put the hood on the character´s head, you can still see the characters face, don’t use just one curved node since the next step requires a good set of nodes to keep the smart stretch right.
add polyfills on the back of these curved nodes, you’ll have to add some other nodes to make a runded baggy shape of the usual hoods, I left two of these nodes movable so I can correct its position when animating.
Finally, add an ellipse or more to give depth and volume to this hoodie, all the nodes I mentioned early should be over the head but this ellipse needs to be at the back since it’s just the hollow area of the hoodie.
That’s about it hope you’re shy so you don’t ask any more questions good luck
