I second Pacific Custom Tailors. Great location in the Pacific Place mall and the service was top notch. 2 fittings in 2 1/2 days made for nice suits. Great selection of fabrics and some nice deals. Got 2 suits, 3 shirts and 2 ties for 8250 HKD. If staying at the Conrad or Marriot, can't be beat on location and price for the suit.
