Attempts to Fix Clothing Dye Transfer Created a Bigger Mess?

I did something really stupid and I need some advice, quick! I bought a new blue sweater and a black and white dress. Instead of washing them separately, like a sane normal person would do, I stuck them both in the washer at the same time. And, they each bled on each other. (But not the rest of the clothes!)

So, I took some advice from this website and put the sweater in boiling water and I added bleach to it; my first mistake. Now the sweater is a mixture of brown and white! Then, I put the dress is boiling water (minus the bleach) and now, where it was white, it's a dingy gray color! I got both items on sale, thank goodness and I don't want to throw them out. I was thinking of using RIT to bleach the sweater a new color, but my mom says it's a very messy process. I'm at a loss for the dress! Can anyone help me out asap? Thanks in advance.
