Oh! I saw it - your dd is adorable! Our dress is nearly identical, except our print is different ( has the multicolor print like Kit's). I overdyed the piping to get the color closer to what they used in the 1930's.

My dd is very slim, like yours, and I will say, if others want to attempt it, this is a dress that will bind around the tummy and hips if a child has any, don't you think? It's very straight and unforgiving. Also, it is hard to get the collar just right at the front of the neck. Fun to make though, if you like puzzles like this.
