Buying several suits? Get yourself on an airplane to Hong Kong. Go to Nathan Road. Be accosted by a hundred Bangladeshi salesmen trying to drag you into their tailor storefront. Pick one you like. Day 1 get fitted, day 2, second fitting. Maybe allow another day for corrections. Before you go, do some research on fabric and stuff, and take photos of styles you like. If you don't know what to pay before you set foot in the shop, you might pay too much.
