As for the split of the skirt, it is designed according to the shape and can appear in the front, back and side.
If the split position and zipper are on two opposite skirts, and there is a seam between the two sides of the skirt, then the split should be worn in the front. If there is no seam between the front and back panels on the 2 side of the skirt, it means that the zipper is located on one side of the body, then the opposite slit should also be on the other side of the body.
