Bespoke tailoring is a dying art in HK as it has been in the US. I have yet to meet a tailor younger than 50 here in the US. The situation is probably similar in HK. However I am glad WW Chan is still "grooming" younger tailors. If you visit their KL store, there are many "younger" employees there. I would guess Patrick Chu is only in his 40s himself. However I haven't seen Gordan Yao with a younger apprentice. I am afraid when Gordan retires, his shop will close.
