I have lived in HK for over 3 years now and have used a few tailors by now. I found Ah Man was impeccable, the cuts, the range of fabric etc. The issue was the pricing. About 15k HKD for a suit with 2 trousers is above my pay grade. I tried Ascot Chang and Oscar tailor as well (both in Central) and would advise against. The range of fabric was astonishingly limited. I am now getting a suit stitched from Y William Yu. For 140 VBC fabric, a suit costs about 1050 USD while 110 VBC fabric one costs 950 USD. I have had the 2 fittings so far and I am so far very happy with the choice of fabric, the service, the process of measurement, the fittings - it has had a good feel so far. It gets delivered day after so fingers crossed. I have already decided on the second one, but am waiting to see how this one comes out.
