while looking through Stitches & Loops vintage pattern site.
Butterick 3935* from the 1940s, which is the pattern that Vogue Patterns reissued as Butterick 5281. I definitely recognized it because I had just complained about the reissue's finished garment photo in this post.
Doesn't look anything like the sketch, does it?
Maybe if you buy the original pattern the finished dress will look more like the pattern sketch? It's worth a try. The pattern is still available here for $22 (almost the same as the reissue's list price) in a size 16, which translates to a modern Bust 34", Waist 28", Hip 37".
