Abstract: A collar straightening device worn underneath the shirt collar that encircles the sides and back of the neck and is held in position by adjusting its length to exert force against both the top button and mating button hole of the shirt. The back section of the shirt collar also provides resistance against the device which when extended to adjustable positions holds the shirt collar in a straight and upright position. The ends of the device that grip that both the shirt button and button hole are fashioned to hold removable design elements that are decorative in nature, allowing the wearer to change different fashionable design elements as desired.
