[Ansteorra] Sorta OT: Fabric Discolouration help

[Chelsea Williams]

Greetings,
I turn again to the great people of Ansteorra with a question that I can 
only guess someone would know the answer to.  My friend's wedding dress is 
partially discoloured due to hanging in a dress shop on a hanger. Is there 
anything that can be done to restore the colour besides bleach? I just 
mentioned it and she panicked. If I was to make a guess as to what it's made 
of, I would say it's satin.  If anyone has any ideas please reply. Thank 
you.
