SK, the answer that you seek will not be found in SF, unless there are people here with examples from both tailors. The examples should also be recent as the quality has changed. The examples should also be assuming full fittings since I would hazard a guess that many here have only experienced Chan oversea visit suits which in theory should not fit as well as those in HK that can go for multiple fittings. Since you live in HK why not go to both places and examine their samples. Talk to the tailors and see if they make you feel comfortable. Then you would be in a better position to judge if it is worth it to you.
Word of advice, tailors charge what the market will pay, and if they are extremely busy they will be able to charge more. Not unlike popular brands there is some premium in the brand name as well, so a popular brand you are getting some assurances of the quality and will have to pay for this.
Understood and very logical answer. I guess it is inevitable that I would have to end up doing some trial and error. :) My goal was to minimize that error by getting as much info as possible, go to the one I felt was best (based on information gathered) and hope that one sticks. If I'm happy, I'll just keep going back.
I guess looking back, it's obvious my other motive was to check which price point was my "sweet spot". Of course I will get more with Chan, but would I have been happy with LB (i.e. as a newbie, does it make sense to pay 6000 more for something I can't/don't even appreciate).
In the end, I'm just trying to cheat a bit with all your knowledge/experience, but I know I'll have to put the money down at some point. :)
