As an update, I wound up buying 2 suits from Dyon Chan of TAKLY Custom Shirts (yes, they do suits, too) in the Galleria, 2nd Floor. Mr. Chan came to my hotel when I arrived (around noon) and by 6:30 he had one suit cut out and did a fitting. I had to leave the next morning, so I didnt have the benefit of additional fittings. I got the suits about 10 days later via USPS and they were almost perfect! I had to have some slight alterations done here at home (would have been unnecessary had I been in Hong Kong longer). Mr. Chan certainly made my 1 day trip to Hong Kong even more worthwhile! Also, he is a very pleasant and charming man, and his wife works in the shop with him.
The suits were not cheap, coming out to about 21,000 HKD, but the material was some of the finest I have seen and felt! He has materials that are cheaper and that are more expensive; you can go with what you can afford.
I HIGHLY recommend Mr. Chan.^
