Abstract: A stretchable, adjustable support device for clothing shoulder straps which connects together straps worn near opposite shoulders and biases shoulder straps worn near one shoulder toward those straps worn near the opposite shoulder to maintain each in a centrally located position between the wearer's neck and one of the wearer's shoulders, thus preventing the straps worn near either shoulder from sliding over its adjacent shoulder. The ends of the support device may be connected to the shoulder straps with hook and pile types of fasteners or they may be permanently attached to the shoulder straps. Applications may include, but are not limited to, use in supporting straps of brassieres, slips, camisoles, and swimsuits.
