Click here to find a free pattern from the V&A for (I think) the dress above. It's in UK sizes 10,12, & 14 (I have no idea what those sizes are in Red-Blooded American, but I'm assuming that's something that's Google-able), and it prints on A4 paper (of which I used to have a stash but don't any longer). So all in all I'm not certain how easy this will be for those outside the Empire to manage, but hey, free pattern for cute dress!
Many thanks to Nora and Catherine, who sent me links to this, and to the associated V&A exhibit, The Golden Age of Couture 1947-1957. Which, delightfully, will still be around when I'm in London in October. Hurrah!
I'm thinking it might just be time for me to become a member of the V&A. Have to encourage this sort of thing!
