The term PART OF A SKIRT can be broken down into two crossword solutions: HEM (3 letters) and GORE (4 letters). A HEM is the lower edge of a skirt or other article of clothing, and it is usually folded up and sewn to prevent fraying. A GORE is a triangular or wedge-shaped piece of fabric used to create fullness in a skirt or other garment. It is usually inserted between two panels of fabric and sewn together.
