I'm in the planning stages of putting a Greedo outfit together and one of the first things i'm thinking of tackling are the coveralls. I've found a go-kart style racing suit that would be ideal-it has the right collar and everything but they only come in white. Has anybody tried dying flame retardant materials and with what level of success? I'm just worried that any coating the material has been given will stop the dye going in properly. Any ideas are most welcome!
