Hi Stephanie,
I heard from a textile conservator who thinks, based on the info you've provided, that steaming could be an option. However, she'd like to learn more about the dress so that she can advise more definitively about what techniques would be appropriate. She said she'd be happy to have a phone chat with you about the details, so I will message you separately with her contact info.
If you'd be willing to come back and share what you end up deciding to do and what factors go into your decision, I'm guessing that there are others here who might also find the information useful.
Thanks,
Rebecca
