This costume came together pretty easily!
Needed:
black shirt (I also added a black long sleeve as it was cold!)
For the shirt, I added blue fabric to the sleeves, gold ribbon to the top and bottom and painted on the design
For the skirt, I used green fabric with flower ribbon. If you want to get technical, you can paint each of the panels on the skirt.
Overall, I loved that I was able to dress in theme but also not be just the typical Anna and Elsa.
