@Figgles- Have you heard of RIT dye before? You can buy it at Joann's and from what I've seen of my friends using it, it looks really easy. They just threw some of the liquid kind in their washer with the clothes they had and let it run. The clothes came out great, just remember if you use that to run your washer again to make sure there's no more dye in the clothes.
Also if you mess up on getting a color too dark RIT also sells a fabric lightener so you can get it to the color you want, or so you can get it a bit lighter to try again.
EDIT: Also you probably will need to style a wig for the charater (Early in the morning and I goofed up on something, durp) I don't know how familiar with wigs you are but may I suggest
amphigory.com if you plan on wearing one (which you probably should if your hair is not exactly like his). They take a bit longer then
cosworx.com to ship out but if your looking for a wig in a natural color or short style I think they are the best you can go to.
