I had already made a pillow case dress for my oldest, but wanted to alter the look a little and give it more personality. So I added a ruffle at the bottom, and a waistband that fed into the ties. The fabric is from Amy Butler.
My little one loves it, and requested to wear it for Resurrection Sunday. Next time I think I will make waist notches on the inside. That, I think, will complete a shapelier effect. With all this altering, the pillow case dress is not as simple as it is meant to be, but the result is a dress that's totally custom.
