Abstract: An adjustable collar having a finished slot through which a fabric strip passes unimpeded. A pair of flaps is formed by an outer band of the collar and abut the finished slot. The fabric strip is secured to a free end of an elastic strip, which is secured to a shirt band at a first end of the elastic strip. A button is secured to a free end of the fabric strip and the button passes through a horizontal buttonhole defined in an end of an outer portion of a neckband of the shirt. The fabric strip is retracted and hidden when the collar is open. The button is larger than a diameter of the finished slot to prevent the fabric strip from retracting completely therethrough.
