Billybats. In essence you gave 10/10 to Chan as it is imopossible to get real all season fabric in HKG. If you are in always (24hour) in AC room, 8-9 oz or 9-10 oz fabric (Dugdale NFW or HS Crispair or HE Frontier) may be used all year around. I wish your Wanchai tailor can do a good job of replication. It is not a easy thing in realty. May I know which fabric Chan used for your suit?
