I hate to be the second bearer of bad news, but I'm pretty sure those are SBS dresses. That's why they are only hemmed on three sides, and the notch in the top is where her elbow covers that area. Doesn't mean that's what you have to do with them. You could overlap them, arranging them them into a circle and applique a center over all. Maybe you could overlap them into an "S" shape. Play with them.
