Basically any, but quality highly depends. I cannot handle dresses well at the moment.

Buttocks area also, its the same kind of problem. GND4 Morph changes the figure lots in the hip area. That makes distortions occur in the morph.

Ah well, I do not know if I can fix that easily. I need a technical way of pretending the gap between left and right leg didnt exist at all. Fill the gap somehow, with dummy geometry or such, something that is easier to match the cloth against.
