I actually ended up using the same main fabric as the jacket in the example photo because I loved how charming it was :). I love that the coat has buttons, but didn't require any buttonholes!
I chose a super soft pink flannel for the lining.
It fits her perfectly! If you're really observant, you'll notice that in the photos of Lucy wearing it, there are pockets on the coat. I decided to add them because the "finished" coat, seemed like it was missing something. I LOVE the pockets!
