These triangular pieces of fabric, available to blend in with everything from casual to bridal wear, are attached to clothing using removable, double-stick adhesive strips. Designer Lisa Leitch explains her inspiration, "It's often too hot or too bulky to wear another shirt underneath, and I was tired of safety pins ripping my garments. I always saw my blouses as missing a piece in the cleavage area . . . so I made the missing piece!"
