One of my favorites, Tiana's wedding dress from the Princess and the frog. I love this dress, but I would want to make it most since I'm Tiana. Yes, I'm a Disney Princess ;)
Anna's coronation dress from Frozen. One of my all time favorite Disney costumes!
Jacqueline's green dress from Ever After. The costumes in this movie are amazing. If you haven't seen it already, go and watch it. Like right now.
I love this Rapunzel cosplay based off of the concept art! Some of the concept designs had some beautiful costumes in them and I would love to make some of them one day.
And on the historical side we have a beautiful green 1860's dress.
What are some of your favorite costume?
