Good luck, Happy Thanksgiving, LUCKIEST
I am guessing that if you find a decent clothing manufacture, they will be able to do whatever designs you want them to. I would think it is more a matter of how much they would cost. What I would suggest is researching normal manufactures and once you get a list of reputable ones, ask each what they would change for your historical designs.
I am just starting to get everything together for my business, and I have a need for a manufacturer. My business will make historically correct Woman's dresses, and I need someone to make those. My question is does anyone know where I can find someone that can manufacture my designs for this venture?
