i wouldnt want to dye it sopping wet in a bucket or washer few wedding dress fabrics would stand up to that , try rit dye watered down in a spray bottle maybe? it would give you a very uneven look which in my opinion would be great for a dug up bride, id hang it up on a hanger and spray it blotchy unevenly in fits and starts and let it dry a bit then go back to it,id do it outside so the dye mess would be less....
