Linda, many others chimed in with very valuable advice here, which I've taken and found successful - not only with this dress but even more similar garments I've started cleaning. I originally had a bit of hesitation about washing the dress at all and, as I said, the safer and less harsh methods to clean the dress worked fabulously. I also fear chlorine bleach may harm garments in the long run (especially ones with so much more age and history.) However, if you have any sources about oxygen bleach rotting fabric faster than chlorine bleach (since I've heard the opposite), I'd like to read more about it.
Also, I see no point why you've bumped so many threads (dating back to May) to add your 2 cents and I think you may need to rethink if you're actually being helpful or rude. I absolutely adore and appreciate this forum because of how knowledgable and kind the members are, so it seems disrespectful to them to barge into posts as if they hadn't taken the time to post. I've learned so much from here as a consumer/collector, not only from my own inquiries but I may be a bit happily obsessed with reading other posts as well, so it's kinda discouraging to see condescending replies from someone.
