"I'd compliment the client on having such a strong vision and thank them for their diligence. You need to accept the client for who he is and agree with him: it's never useful to openly disagree. Then I would ask the client why they came to us specifically and not another tailoring house. If he tells me that there is something unique about our style, I'll remind him that we specialize in this particular style and that he came to us for a specific reason. If he insists and his mind cannot be changed, then I'll defer to my superior and let my superior make the decision."
