aw what a shame, is there anyway i can fix it? even if its temporary i dont mind.
I don't know. I'm not even sure if that's the problem - I don't have that much experience with metallic fabric - but that's my best guess. I did just find this site that mentions some of the issues with lamé fabrics, which sounds similar to the problems you're experiencing:

You could try painting the light areas with metallic fabric paint, but it will probably be hard to match the color exactly. Any fixes will probably just be minimizing the damage rather than truly repairing it, though. I haven't used any metallic fabric paints, so you should do some research, read reviews, before deciding. I see Amazon has several different brands avaiable, that could be a good place to start.
If you do decide to use fabric paint, I'd test it on some scrap fabric if you can, preferably the same type of base fabric ay least. You can also test a small area of your costume that isn't too visible, just in case.
