Shauna from Shwin & Shwin shares a free pattern for making her Fallen Top for little girls. It gets its name from the falling triangles she embroidered down the front. It buttons up the back and has a color block high-low hem. The free pattern is for a size 3T/4T. If you need a different size, you could probably draft your own pattern using hers a guide. Go to her blog for the pattern and tutorial.
