A Dong Silk is a highly marked tailor on tripadvisor.com. Their clientele (the clientele of tripadvisor.com, that is) are notorious cheapskates. I had 14 shirts, 12 trousers, and 4 suits made by them about 6 years ago. They've worn very poorly and are not the fabrics they represented - 100% cotton shirts are cotton/poly blends.
The jackets of the suits are coming apart - they appear to be somewhat glued together.
If you have special tailoring needs (crooked back, leg length differences, etc.) you really need to speak up for yourself. Usually there's a salesperson who isn't a tailor doing all of the measuring. If you have special needs, you'll have to insist that the tailor come out and have a look.
If you get a mens suit made and don't have at least 2 or 3 fittings before the jacket is finished then they haven't really done their job. It's just not possible. It's like if you told your kid to take out the trash and they come back inside 5 seconds after they left. If this happens, you're not getting a well made product and you're usually too late to back out. You'll have to make demands about the fit and finish and you likely won't/don't know enough about clothes to do so.
Finally, recognize that you are not capable of telling the difference between egyptian cotton, cotton/poly blend, wool, wool blends, cashmere, etc. Further, if the material is presented to you in a deceptive fashion, you're really gonna be screwed.
Use somebody you trust. Use somebody that's not super duper cheap. Do not count on tripadvisor ratings. Gather ratings and reviews from elsewhere, and be prepared to spend money. It's like they say: fast, cheap, good - pick two.
