Two years ago my boyfriend and I went to Disneyland Halloween Time as Tiana and Naveen from Princess and the Frog.
I made both of our costumes. I used a pattern for a basic strapless top, so I had to completely improvise all the leave parts of it. It turned out so well!
Before I added the leaves. (the bodice and skirt are not attached at this point)
After adding leaves. (the middle one is flopping down)
