Poser Fashion had several different eras of dresses, but that doesn't help. The site (alas, gone forever) that had all this stuff was Lannie's 3d world. Tons of Victorian props, Bryce Mats, but it was hogged out of existence by download accelerators. You could probably use the Wayback Machine to pull up the text and pictures, maybe there's a links page that would point to some sites that may still be in existence. Slim thread, but it's all that comes to mind.
