I assume the question is genuine.
I think this is the maker.

I am not sure if there is a dealer in HKG or sell direct to tailors.
If you ask around ShamShuiPo area, you may find the shop that sells those.
As Chobo said, everything is too hot if you are outside in HKG humid summer.If you go finer fabric (sub 8oz) you can only wear in summer time and tends to be not so durable.9oz Dugdale not a summer fabric IMO but wearable longest period of the year except coldest and hottest months. Nice choice of fabric and I would not blame sales rep explaining it to be "all season".
Billybats. In essence you gave 10/10 to Chan as it is imopossible to get real all season fabric in HKG. If you are in always (24hour) in AC room, 8-9 oz or 9-10 oz fabric (Dugdale NFW or HS Crispair or HE Frontier) may be used all year around. I wish your Wanchai tailor can do a good job of replication. It is not a easy thing in realty. May I know which fabric Chan used for your suit?
I agree. Time frame is simply too short to make jackets or trousers done properly. You may get wearable/passable/fitted shirts made. Get measured in the shop once and shirts being shipped to your home. Your time and financial damage limited.
I understand that some test shoes mean their gauge shoes to check your feet. I checked their web site and they make adjustment based on your foot length, ball girth and instep. Test shoes may have softer leather to show the creases easily to check the fit.
