Help! Ruined top! What to do???

[feelinghopeful]

Please help if you can as I love this top and it is a "special" one!
It's a white summer top, rather like this one: www.phase-eight.co.uk/fcp/product/phase-eight/Tops/Mimi-Silk-Blouse/500890151
A jersey base and then a silky blousy bit over the top.
I carefully handwashed it, but as there was a mark I left it to soak in bleach...
MISTAKE.
The silky blousy bit has now gone a horrible brown washed tea-bag colour.
Is there Anything I can do??
It's totally ruined at the moment, so am willing to take a risk... !
Any ideas totally welcomed. Thank you.
PS made of silk and viscose

Dye it? Silk and viscose are both natural fibres and will take dye really well. Though it may well be sewn with polyester thread that won't.

Thanks Gobblers. Is it a well known fact that bleach makes silk go brown? Or was it the soaking that did the damage?
Anyone else had this problem??!
