I'll start making the back side of the bunny suit. Let's start with the panties.
1st, the rough shape of the panties will look like this, since this is a g-string panties.
The horizontal strap is located in the buttock parts, so when the legs are opened/closed, the intersection will be shifted due to deformation.
So I'll compensate for the misalignment by deforming the strap using a tween animation.
OK, this eliminated the misalignment.
Next, make the tightened part by the strap, and cut the excess with a mask. The curve here is difficult every time.
Further, the overhang of the center part is cut by masks placed outside the butt deformation.
Done.
