I made Gracie a new dress today. I used Simplicity pattern #5483
and was very happy with it.
She will be able to wear it with a shirt under it, like I show in the photo, or it will be able to be worn with nothing under it. The arm holes fit her perfectly, (they aren't too low like many jumpers are).
I used denim. I have only made skirts with denim and this was tougher than I thought it would be. The denim was a mid-weight-I knew I didn't want to sew anything heavyweight, but even the mid-weight was hard to work with. It took an hour to just turn the ties that are in the back right side out. (If anyone has tips for doing this with denim, I would love to hear them.)
