Here's a Cupcake Dress FREE Pattern. It's a simple silhouette with elastic in the back for a comfortable fit, ties around the neck and a gathered skirt. It can be fully lined or just lined in the bodice depending on how sheer your main fabric is. The bodice prints on just two pages and is available in sizes 12M-8. For the skirt and straps, you just have to cut some rectangles.
