The most important part of a historically-accurate silhouette is a good foundation. (And a historically-appropriate amount of cleavage-- IF ANY-- but that's a rant unto itself.)
It's not perfect, but it's a good start. Looks better on me than on the dummy. By Friday, I want to have the bustle finished. Stay tuned, cats and kittens.
In other news: my dress dummy needs a name. Any suggestions?
