Yes it might be a long shot but I want to try this method of bleach
out the design in velveteen and redye the sections lighter blue. I will be making this section out of the extra fabric I got rater then ruin the dress fabric if it doesn't work i still have my standard dress. I'm also most certain they don't sell Soft Scrub in Canada so I'll be looking for a alternative.
Tho other option is to strip the extra fabric and redye it the lighter colour then cut and sew the pattern on. I want the texture to be the same otherwise I you go with a other fabric in a lighter shade.
The Disney parks dresses are actual two tone with the lower section is in a black background for the design.
Tarnishing makes everything look better.
