We sell lady's kilt skirts of all lengths.

Ours are all made to measure, so you just tell us how long you want it and that is how it is made. Unlike men's kilts, which are always knee length, there is no standard length for the ladies. In my experience, anywhere from just below the knee to mid-calf is common. But I've taken orders for everything from 14" long down to floor-length.
