/cgl/ - Cosplay & EGL

Help me, seagulls!
I recently received a dress that I'm totally in love with, but the seller completely lied to me about the condition of. The bottom part of the print is supposed to be white, but not its a very faded yellow-gray (ew.) I've already hand washed it to no avail, and I have no idea how I could fix it.

The trouble is, I still really want to wear this dress! Here's what I have already as a coordinate for it. I'm planning on black tea parties and a black wool beret to finish it off. My question is, is this dres even salvageable? Should I even try?

Thank you!
