All about the costumes of Downton Abbey, and actual clothing from the time it's set.
I generally post in series, and I love suggestions of topics or designers or other stuff that people specifically want to see, just because they want to know or because they're doing research for a fic.
Whenever I post images of extant clothing or fashion plates from museums, I give the full citation with accession number, museum name, title, and date - you just have to click on the picture to see it.
