Ahhhh, yes the synthetic materials and scarlet as black dye problem. 
You can actually see this in advance by taking a REALLY close inspection
of the material, shinning the sun or a bright light behind the material
or take s "snip" test and wash the material to "see" what color the dye
was.

Use cotton, silk or wool to make sure, but...testing IS ALWAYS BEST.  If
you don't have that luxury, use a couple of different outfits made of
different materials.
