The poor dress was in such bad condition, but at least now it looks like a dress and not a dishrag. There is a label inside that says "Oppenheim & Collins, Co." This was a women's clothing store established in New York city in 1901, and in Buffalo, NY in 1905. (http://en.wikipedia.org/wiki/Oppenheim_Collins)
This is the front of the dress, I believe. There is an underlayer of silk that has completely disintegrated, and the brown net trim is very fragile and is staining the cream color. But the beading is fairly intact.
This is the dress from the back. I don't know if the low V was possibly lined. I am also guessing about the placement of the beaded belt around the waist. There are several snaps and hook and eyes that I cannot match up. But there was some mending done on the dress before I did any, so it is possible someone else moved things around.
The dress is really too fragile to hang up, let alone wear, and I think it will be placed back in the dresser at the museum for the next person to discover.
