I was going to start a suit business in the UK so I know a fair bit. First of all what is your budget? Bespoke suit are not cheap if its actually bespoke. Some tailors will try to say they are bespoke when they are tailor made. Ask how many measurements and fitting they will cater for you. What is the base price (they would know the cheapest cloth they have + plus labour) - providing you are not asking out of their normal finishes, e.g details like hand sewn button holes for example. Are the jacket full/half canvas? What type of canvas they use? Is the canvas fused or hand stitched (hand sewn obviously more expensive and it falls better)? What is their house cut? What shoulders do they normally have (e.g. UK tend to use shoulder pads and Italian tend to use almost no shoulder pads).
