I'm afraid this is not guaranteed to yield a truly white jacket. It's hard to get all of any dye out enough to make it truly white (you're more likely to achieve a beige), and some dyes cannot be bleached or removed at all. Dye removers other than bleach require heat, which might not be good for fake fur, and of course bleach itself will permanently damage synthetic fibers such as polyester.

You could give it a try, though. While color removers such as Rit Color Remover (sodium dithionite) and Jacquard Color Remover (thiourea dioxide) work best when heated on the stovetop, you might be able to get some color removal just by using the hottest tap water you can, in a five-gallon plastic bucket. Be sure to stir a lot, or the color may come off unevenly. Both Rit Color Remover and Jacquard Color Remover are safe to use on polyester, unlike chlorine bleach.
