Abstract: A clothing clasp for shortening the length of a strap of a sleeveless garment includes a frame member providing an opening therethrough and a cooperating insert member having a raised area that can fit in the opening when positioned beneath the frame member. A portion of the strap can be pushed downwardly through the opening to provide a loop, and the insert member can be positioned within the loop so that its raised area will extend upwardly in the opening and remain there with tightening of the strap and reduction of the loop.
