Pricing will depend on what cloth you pick, whether you're having a two piece or three piece suit made and, for you guys who are in a rush over CNY, some kind of extra payment to keep the sifu hard at work.
Gordon is charging me slightly more than Chan would do to make a two piece suit in Fresco. It's only a matter of 2% but still this rather surprised me - I thought Chan were way out on their own when it came to charging. I am 6 foot 1 inch tall and probably about a 44R so I guess they'll need between 3.5 and 4 yards of cloth to make the suit. Fresco is sold through the Minnis website at about US$100 a yard, though that's the price including 20% VAT which wouldn't apply to an export order. So for an US$1850 suit the material costs between 15 and 20%. A strongly checked fabric might require more cloth to get the pattern matching right.
I've reflected on what I wrote earlier on this thread:
1. The finished work that Gordon Yao produces does look very good. Have a look for their official SF affiliate thread and drool away. Gordon doesn't hold back when it comes to advice either and will offer you either British or Italian styling. He's a good guide to have as you take your first step into this confusing business.
2. For men with relatively regular bodies then having a straightforward two-piece suit made in a "normal" suiting cloth, with notch lapels, flat-front trousers and belt loops isn't necessarily the greatest use of your money. There are a lot of quite good RTW options for you that will look fine with some alteration work. Bespoke becomes more valuable if you have an odd body shape, sloping or dropped shoulders, long arms, short torso or some other feature which makes it harder for you to find a well-fitting garment off the rack. Or you want features which are dropping out of fashion but not style, such as single forward pleated trousers. Gordon looked me up and down a few times before licking his lips and saying "You have an expensive body... nothing is going to fit you off the rack". Hopefully the finished suit will bear out his words.
Where bespoke is also best is when you want to use the finer suiting cloth, perhaps with more colour, texture or pattern than the menswear industry likes to put out into department stores. Also you can start to manipulate details and proportions to change and improve your silhouette. Shorter men find that peak lapels that reach fairly high up their shoulders but which stay fairly narrow can elongate their bodies and make them look taller. Thin men can find a wider lapel and slightly extended shoulders give them an impression of more breadth and that masculine V-shape in front. Fatter men, like me, are just grateful to be inside something that isn't an actual sack...
You can also have details such as slanted pockets, a ticket pocket or a fancy lining. I'd personally stay away from all three for your first suit but hey, it's your choice.
So do keep doing your reading and research. Don't get suckered into going for a cloth with a higher Super number just because "it's better". Thomas Mahon's blog "English Cut" has a good article on this topic as well as several others that will add to your understanding.
The best reason to pay top dollar and go to Chan or Yao is to establish a relationship with those tailors, with a view to acquiring more garments down the years. Both promise to keep your measurements and pattern on file to make constructing future suits easier. Whether either actually rip down your basted fitting and transfer the alterations back from the cloth to the paper I don't know. Yao has a big file of measurements (I'm pretty sure I saw the details of the body shape of another SF member, catching a glimpse of his business card and putting that together with what his profile says about location and job). Chan actually do have paper patterns - I know this because it came out at my first fitting to show the belly shape of the lapel. Of course once you've started down the repeat order trail then there are no limits
Whole thread is worth a read.
