For SD girl stockings I used the meassurements of a CP Lishe. But these stockings should fit other SD girls with similar size as well.
PLEASE NOTE: Overknees may fit very tightly on Elfdoll girls because their thighs are a bit thicker than CP's. (I've tried them on an old ED girl body.)
If you have any question just convo me. I will reply as soon as possible.
