There was really no information provided about this particular dress, but I am guessing (based on the presentation in the photograph) that it is a museum piece somewhere.
Check out the website for tons of other amazing period clothing ~ both from movies and museums. The blog has some pretty amazing movie stills and publicity/costume shots so you get to see some incredible detail on the costuming.
Will be posting more original dolls (clothing!) this weekend!
I will definitely be stealing these designs for my own characters when the time comes to work out their 1860s ensembles.
I love how vivid the colors are. A woman photographed in this dress would have appeared to be wearing black as yellow and gold tones in sepia prints translate very dark (I should probably find out why, but it's true).
This dress is identified as being from the Metropolitan Museum of Art Collection.
