The biggest Disney princess (at least, at 2.35 million cubic feet, by volume) has to be Princess Epcot. Cosplayer @skygetsfancy made this dress inspired by the Spaceship Earth geodesic sphere at the Epcot Disney theme park. She writes:
This is one of my absolute favorite photos from this shoot, I love how much of the tetrahedron skirt this photo shows! I studied the pattern on Spaceship Earth A LOT and went through several patterns to figure out the perfect height and width for them. My original design for this gown actually included them going up into the bodice too, I’m way happier that I went with this version!
