Although, could someone enlighten me as to why you would want to discourage CMT? Look at the numbers: let's say my cost as a tailor to change a length of cloth into a coat is 1000, and I use cloth worth 500. Markup on both, 50% Total cost: 1500, profit:750, customer pays 2250. Now let's say customer brings own cloth. I lose the 50% markup on the cloth, so I raise my markup for the tailoring: rather than 1500, I charge 1750. No profit difference to me, if customer wants to pay the retail prices for fabric, that's his own problem. Of course, I can imagine there are some problems related to things going wrong. That's why the tailors I frequented, at least, explicitly warned me that if anything goes wrong, it's my liability and not theirs. I can also imagine tailors not wanting to work with substandard cloth, but when something comes from Minnis, London Lounge, Harrisons, or whatever, that is not quite the case. So am I missing something here?
