If it's not too long, tie a thin belt. If it is too long, divide it into five or six areas from the bottom of the skirt. The size of each area depends on the size of the skirt and should be uniform. Then use a needle and thread to pick it from bottom to top, which not only looks good, but also does not need to be cut off to change the integrity of the skirt. Maybe one day a long skirt becomes popular and a new skirt is torn off.
