I love quick & easy patterns for my kiddo! And Simplicity 1435 seems to be my go to pattern to make a quick outfit for my 4 year old. On this particular outfit though, I did not use the ruffled skirt as suggested. Instead, I just made a simple gathered at the waist skirt to attach to the bodice. The pattern also calls for "knits" only, but I always add a zipper to the backside & it fits perfectly fine. Bias tape around the neckline & armholes & its done!
I paired this dress with some basic burmuda style shorts, which I also sewed up using some white knit fabric, same pattern just shortened the length & made a wide hem.
