There was a long discussion about tailors a year or 2 ago (so it would be in the archives, making it harder to find) and the net was the consensus that HKG was too expensive now while BKK was not as good but much better value and a couple of specific tailors in BKK were almost as good as the best in HKG but for 20% of the price. I forget which forum but it was a travel forum, not airline (maybe Hong Kong) and don't have time to find it now.
