With the shoulder strap retainers in silk finish, the slipping of vest or bra straps is prevented when wearing sleeveless clothing. They are sewn into the shoulder area inside the garment. The straps are guided through the flap, which is closed with the press fastener. This allows even wider straps to be held perfectly in position. The shoulder strap retainers are made of 100% polyester and are equipped with a stainless press fastener made of brass.
