biped skinning problem

[Francisco Penaloza]

Hello every one, I been having problems with this animation that I'm working on, I work doing Arch Viz so I'm not specialized in character animation or so, I just do basic Biped walk a seat animations,

now for this project I need to animate several people but most of them are woman with long skirts

I did set up the biped and skin modifier everything work fine but the skirt look really bad, I did tried Physic but it look worse, what is the regular work flow for this type of model?

Long skirt woman??

should I try a cloth simulator for this part?? but my fear is the mesh load at render time, I need at least 50 people walking around

thank you in advance
