This would be a good start:
Adjust to your budget accordingly.
I ordered a pretty standard conservative two-piece, two-button, notch lapel suit made up in Harrisons Premier Cru #51410. I will be in HK in Sept for two fittings. Looking forward to it.
I looked at the Minnis books for the frescos and they were pretty rough in my opinion. I think I will go with something from Harrisons Frontier for a navy hopsack blazer.
