I have a dress that I love dearly, but the pattern on the fabric was all kinds of wrong. It was this crazy pink/yellow/orange/lime green 60's mess. So, I got some rit dye and tried to dye it navy blue. It didn't really work. Some parts turned purple and some parts turned dark olive. The pattern still shows through but in the ugliest color. What can I do to get it all one color? Should I just keep dying it until it is all one color? Bleach it and then dye it? I'm at a loss.
