My Minnis suit at Practical Tailors ("PT") was HKD9,700 for fully-canvassed, half-lined (forget the name of the fancy lining but I believe it was 100% silk rather than a silk / polyester blend which many other tailors carry) with a Milanese buttonhole. I've used a number of tailors in HK including Lee Baron, William Cheng & Son, Il Sarto and New Century and I'm very much pleased with the results at PT thus far.
The proprietors, Andy and Jason are ex-Taipan Row ("TR") from a number of years back (when I believe the TR name still stood for something) and as they tell me they combine the cut and fit of a Cantonese tailor with the workmanship and finishing of a Shanghainese tailor. PT also differ from alot of other tailors in HK in that they have their own "kitchen" and so have better control over quality and timeliness in terms of delivering product.
My Minnis is currently in their kitchen getting some final alterations (letting the jacket out slightly at the waist) so I'll post pics when I get around to collecting it.
