I figure I'm saving quite a bit by using my own cloth. My tailor has quoted me about $800.00 to $1,000 additional to supply the same cloth I can purchase for about $200.00. Almost every tailor I've ever talked to marks up the fabric by a factor of at least 200% to 300%. I'm willing to believe that a bespoke tailor has given you a $1000 discount if you bring you own cloth but let me tell you: that's not a common number at all. Most tailors who do CMT will not cut that much. I use one tailor who does CMT and procures fabric too - the difference in price vs what I can purchase myself is maybe $100.
