Here's the formula: a white bodice with a lace overlay (which I usually accent with some glass beads), plus a print skirt that has a lot of white in it, plus a pretty lace or other trim at the hem, equals a dress that is light, delicate-looking, and sweet.
Sometimes I go all-out and add a color-coordinated sweater and a hairbow made from the skirt fabric, to complete the ensemble. I offer these sets in my Etsy store occasionally.
