Extra detachable collar for a Khaki Shirt. Officers normally purchased their uniforms from a tailor or officer's outfitter, although some items, including shirts, might have been obtained from QM stores on repayment. Officer's shirts were generally tailored and had detachable collars, following civilian gentleman's fashion of the time. Collars were held in place by metal or sometimes ivory studs. Neckties were usually green or khaki cotton or silk with Service Dress and wool lampwick with Battledress. The necktie and collar were often secured by a metal collar pin.
