So I'm trying to find a solution - I need to dye a cotton suit, and another RPF member gave me this advice. Because of the heat needed to make the dye work:
"The issue you're going to have is that suits are made with fusible interfacing. There's a good chance that will all separate from the fabric on the inside and the lapels and whatnot will all lose their shape. Also, the cotton will shrink slightly, but the liner probably won't, which could result in liner peaking out of the cuffs and hem."
What does everyone else think? Is there a dye that works at lower temperatures? Or something that will help "set" the interlacing?
