My first thought was it is a tailor made British or Australian Officer’s aertex shirt Late 1940’s or 1950’s. Made by ‘Lee Cheng Wah, officers’ tailor’ General HQ Farelf Tanglin Barracks Singapore. As this barracks was also responsible for a small Gurkha division and a small Malay Regiment, it is possible it was made for one of these forces. I believe there was also a contingent of Indian troops. Most definitely a post WWII item due to the marking HQ FARELF (established 1947), due to the style it could well be late 1940’s. I can’t find anything about the tailor, was most likely a very small one.
