There are two types of Strap Retainer available:

Safety Pin and Popper:

These come in nude, black and white and are designed to clip (using the press stud) around your bra strap and safety pin to the underside of the garment to keep the two together. They are especially useful to keep bra straps concealed or to keep wayward garments from slipping off the shoulder.

Shoulder Strap Retainer:

This strap retainer is designed to go round at the back between both bra straps to assist in keeping the bra straps together so they don’t fall off the shoulders (see picture). They are 40cm x 1.9cm.
