What is it made of? If it's polyester or acrylic, there's a good chance you are out of luck, as those fibers can't be easily dyed at home. (Some people have been able to do it using very, very hot water, but that's likely to damage any interfacings, shoulder pads, etc. in an already-completed garment.)
ETA: Also, if it's lined and the lining (or the thread, for that matter) is made out of polyester or acrylic, it won't take dye either, even if the shell will.
