It's McCall's pattern 6141 in a girls size 3/4. Or at least, that's the pattern I started with. Bodice was crazy (and too big) so I redrafted the front as a single piece and modified the back to be a bit smaller. The yardage was off by a lot, too, so the skirt isn't quite as wide at the bottom as originally designed. Overall, though, I was able to alter/draft, pin, cut, and sew the whole thing (less the hem and zipper) in less than 12 hours. Not bad. And Addy seems pretty pleased with the outcome, too!
