Hmm, interesting. I did these leggings in a few minutes using the Alyson 2 Developers Kit.

I used the Medium bodysuit mesh. Cut the mesh as required, moved a few polys to shape better and did a single subdivision.

Total poly count 3024.

Did a simulation, used basic settiungs, but had colission at 0.5. Switched off head, hands and feet option.

No poke through.

Silo Pro 2.1 used.

Rendered in PP2012.

All the best.
