I found the pattern online at the fabulous blog The Vintage Pattern Files that has a pattern for pretty much everything you could imagine from Victorian to the 1970s. Browsing the "1930s" tab, I decided on this 1935 Simple Jumper because I loved the art deco-ish neckline.
Paired with a self-made (no pattern used) 1930s-style skirt I made, the sweater goes perfectly. Added a belt for that extra 1930s touch! I am very happy with it. My grandmother knows my favorite colors are pink and red so I'm extra happy. I'm scared to wear it, though, lol.
