I always thought this Butterick pattern and a few similar ones I have were from the 1940's, but I was wrong. I saw somewhere recently that these date to the 1930's. Late 30's I'm guessing. If you know more, let me know.
I like the sundress but I get tired of trying to size up these 30 inch bust patterns sometimes. Granted I don't have to size them up much, but it's not something I enjoy doing.
