The only alteration was to sew the buttons and button holes the opposite way to the pattern. The straps were really long and I didn't check them until it was finished. So I swapped them around and the extra length is tucked down the front of the dress and the button can be moved as she grows.
I love all the top stitching on this tunic. I used an aqua blue to contrast with the almost black denim. I was too lazy to set up the double needle and I find it just as easy to sew two lines.
