Hi There, I was wondering if you can dye another color or a close enough color on a shirt made of 90% nylon, 10% spandex? I got bleach on the new shirt. PLEASE advise. Thanks

This is a hard thing to fix. Once chlorine bleach has touched fabric, it can’t be over-dyed. There are professional services that can fix it for you. Check out www.dyeproservices.com.
