there was a thread over at aaac's... here's a cut-n-paste:
Go to the intersection of Patterson and Orchard. That is where the Marriott hotel is located. Walk north up Patterson a few meters and you will see the Far East shopping plaza. There are several tailor shops inside that will make bespoke suits for you. The vendors are agressive, so watch out. However, they will educate you. You should get at least three fittings.
My suggestion after you visit the several shops, is to go up to the top floor. Check out the shop way in the back over on the right [as you face the building]. The guy there is a no-hassle type guy, and the bespoke suits on display look good. Ensure you specify no glue and completely hand sewn.
I have used Joe's at the former IBM Towers (now known as Fuji Xerox Towers). Good work if you know what you want. Trustworthy styling if you want to follow the fashion crowd, but if you want to be elegantly dressed, you will need to know what you want. Willing to listen and work with you.
I think you had meant to say "Golden Shoe (Market)". The only tailor there was "Just Tailor", which had temporarily closed for renovations 2 months ago. It was owned by the guy who also owns "Joe's Tailoring" at Fuji Zerox Towers. They do have some skilful craftmen but as pchong mentioned above, you will need to tell them what you want (not that they will not advise you if you ask). Request for more handiwork and you will get them. They also have an extensive range of high quality suiting fabrics and shirtings. Quite a "high-end" establishment by local standards and a lot of their clients (expatriates and locals alike) are/were from the financial district.
There is another well-known tailoring establishment called "Anson Tailor". "Anson tailor" has 2 branches - one in the second floor of "Republic Plaza" and the other in the basement of "Hong Leong Building" - in the financial district. The owners (2 brothers, each run a branch) do a lot of their own cutting and seem quite knowledgeable. I have not used them before but have heard some good things about them. By way of their locations, they are definitely not tourist traps and people who find their way there either work in the financial district or have been recommended by people who do. Also quite a "high-end" shop by local standards.
Also, there may be some confusion about "Far East Shopping Centre" and "Far East Plaza". These two buildings are within about 10-15 minutes' walking distance of each other and both are home to quite a few tailors.
"Far East Plaza" is a lot bigger and has many other retail shops and fast-food outlets. The tailors there usually more aggressive. As it is a large (but past-its-prime) shopping mall, I would imagine a lot of their clients are walk-in tourists. "Kingsmen" (mentioned above) - quite a well-known establishment which has been around for a long time - is located at "Far East Plaza".
"Far East Shopping Centre" (next to "Borders" bookstore) is a much quieter and smaller building. There are quite a few tailor shops there and they are less aggressive.
had a couple of shirts made at an establishment in far east plaza couple of years back... from "jack's" on the 2nd level i believe. apparently this establishment (and i assume the rest of the lot) has a good variety of fabrics to choose from, and they have their own set of repeat customers, as the proprietor was telling me. quality is on the average, though they are more expensive than the ones in hongkong. but for suits, i think i'd avoid far east altogether.
