From Natural Knits:
I love to dress little girls in knitted slipover dresses--they are so simple and versatile!  This design is worked in two colors, and the flowers are knitted separately and sewn on.  You can change the look easily by using only one shade for the dress and lots of colors for the flowers, grouping them in bunches, and adding stems with embroidery.
