While I'm working out the last kinks, here's a handy tip for simulating skirts. Probably common knowledge, but bares, pardon, bears repeating for the benefit of slow-learning newcomers like me:

To avoid unintended panty-shots in certain poses, as shown on the left, it can be useful to spread the knees wider apart mid-simulation and bring them back in later. This collects and entraps a larger amount of fabric between the legs that can subsequently be pulled down by gravity to cover up the unfashionable underwear.

(LF2 is looking very serious here because indecent exposure is a serious matter.)
