I believe?

I got this second hand at a swap meet and the closest dress I can find on lolibrary is linked below. It has some variation, which leaves me to believe it may have some pieces that have gone missing/been exchanged over time. It's a heavy dress and super comfy. It's got some wrinkled lace that needs sorted out (see pictures)
It is fully shirred and has quite a bit of stretch, but I'm cautious as to just how far it can stretch because it's not quite as forgiving as a shirring princess. I'm a 42inch bust and it fits comfortably. I'd say it could probably go bigger, but uncertain as to how much more.
