Interesting. I wonder how the foreign suit makers affect this business. I have a few friends that visit Thailand regularly and get custom suits made (cost is <$200 USD). For the price of one of these suits in NY, you could fly to Bangkok (in Business Class!) AND get a few custom made suits.
Those <$200 USD suits made in Thailand are unlikely to be top shelf. There is a huge business in southeast asia on rapid turnaround custom suits. It's not targeting the same market as real bespoke tailoring.
I have a weakness for bespoke suits. I live in Singapore, and have gone to the same tailor for seven years. He's superb, but you can tell from working with a great tailor why even "made to measure" suits can be disappointing. When I started with this guy, I would go back for two fittings after my initial measurements, and before the suit was done. The fittings would be done with the partially constructed suit. Many details were checked and little adjustments made: asymmetry in my body, the sway in the back, where I pocket my phone, how to adjust the jacket for my wallet, and making sure the right sleeve accomodates my watch (I'm left handed). I thought it was overkill. But worn, his suits are flawless and so comfortable the idea that a suit would be uncomfortable is a distant concept.
After the first few years we reduced it by one fitting.
