I'm not posting any pictures of my corset mockup, because it is disgraceful. But I've taken it in quite a lot around the hips, evened out the bottom edge, and taken an inch off the CB edges. I think the sizing issue might be that the line I made to indicate the hips on the pattern was actually too high, and the pieces of course kept flaring after that.
If you look at the right sidebar, you'll see that I've created pages for current and finished projects, and my collection of extant clothing. All the pages are very much under construction, but there's some stuff up on them, if you'd like to look.
I spent some time today on the New England Museum Association website, and I've found three relatively paid internships that look promising! One is at Old Sturbridge Village (curatorial), one is at the American Textile History Museum (also curatorial), and one is in the Newport Historical Society (museum studies). Wish me luck!
