Those are adorable!
I've seen them used for closet organizers for children - socks, underwear, hair ribbons, leggings, etc. They would be cute in a sewing room for small items.
Without too much alteration the dress could be made into a little sailor suit, overalls, etc. for little boys. Just put a small "v" in the bottom to make the skirt into shorts and then change the color and buttons.
