Most of my suits are actually off the rack Zegna/Boss (I admit it!) but I did buy a bespoke suit at WW Chan in HKG which I'm happy with. The quality is good and while it's not as cheap as you might think for HK, it's certainly not Savile Row prices. For shirts I like Ascot Chang (there's one in the Peninsula); they're not as cheap as they once were but they make great shirts.
