A skirt feature, perhaps, can be a PLEAT, which is a fold of fabric that is pressed or stitched into place. It is usually used to add fullness or decoration to a garment. Another skirt feature, perhaps, is a FLARE, which is a gradual widening of the hem of a skirt or other garment. Lastly, a skirt feature, perhaps, is a SLIT, which is an opening in a garment that is usually located at the side or back of the skirt.
