Banksmiranda: Actually, I think the highest cost factored into a suit is the workmanship and shop-keeping. Â Unless we are talking about big tailoring firms like Brioni or Oxxford, an outside tailor usually orders materials at a sharp discounted price. Â Even with Oxxford, who orders from expensive weavers like Moxon, will never pay 'retail' price on their fabric, as they have permanent contracts of very, very large orders. Â Kiton and Attolini are a little different, as they buy up the entire stock of a particular fabric from a mill. Â Buttons, lining, shoulder pads, etc. are all dirt cheap. Â I am talking about single digit dollar amount for these things. Â Again, unless you are making a suit at Kiton or Isaia, who custom order their shoulder pads in a particular way, an outside tailor usually orders a 'stock order', usually between a layered shoulder pad or a one-piece pad (the former preferred), and the cost of that is a few US dollars per pad at most (I said at most because if you buy in bulk, the layered one cost $1/pad, and that will be the usually used cotton felt/linen canvas pad). Â Lining is cheap too, unless the tailor orders it with his emblem all over, otherwise normal bemberg lining costs about US$10 to $20 (at very most) a yard. Â Interlining, or canvas, at your local tailor, are usually ordered in bulk too, though I am not sure how much; but if you were to look at the roll of canvas that it comes in you'll know that they are very cheap --- again, unless you are making a suit at Kiton who needs a horsehair canvas. Â Labour is different, though usually the person making your suit is not the person you saw taking your measurements (aka tailor or boss), but some other persons employed part-time or even contracted out at outside factories. Â My tailor in New York employs his niece to do all his buttonhole embroidery (which is very well done, by the way), for a mere $5/hole. Taken all these into account: let's say you picked a very good fabric, which will come out to $300 at most (assuming $80/yard), plus cost of other materials at around $100 (if silk lining chosen then more), total material cost will not exceed $400 or $450 (at the outer most, if you picked a super 180s). Â The rest is how big an ego the tailor has for himself.
