This is the birthday girl's dress. It's basically a pillowcase dress with fabric band at the top tied in a bow, and a ruffle along the bottom. The diaper cover matches the blue bow.
The fabric was chosen by her mom.
The older sisters' skirts are a mathematical feat. I used a red and white chevron for the underskirt, added three layers of ruffles, and a layer of red tulle. The top layer has a red ribbon on top. Each of the three fabric ruffle layers were pieced together from a variety of Dr. Seuss fabrics.
Happy Birthday, E!
