Something Thigh-High or with Garters.
PLEASE - There is no way to get the current (non-dynamic) offerings to fit, and stay fit, in any realistic way, on any modified, stretched, bent, muscled, morphed or manipulated leg.
There would be 3 ways to make this work I imagine.
1. Use a reversed gravity field so they do not fall down.
2. Use a garter belt (which can be hidden) to hold them up
3. Use a panel at the top with high Friction to hold them up.
I can guarantee only that *I* would buy them… but I think I am not the only one who wants ‘em.
