I live in South Bay California and have a green dress I wish to dye black; however, because of the polyester I have not been able to succeed. These sites you have listed do not show what area they are in. Anything close to home would help. Thank You

Sorry, no matter where you live, you'll have to mail your dress to a distant location to have it dyed for you.

Nobody will dye a dress that is not washable. The only company I've read about that indicates a willingness to dye a 100% polyester dress is Color Creek, in Alaska. You can mail your dress to them, after contacting them via their web site to make arrangements.
