Have you ever worn an incredibly full skirt? Some of my fondest costume memories are of wearing hoop skirts. Granted, I would not want to wear one every single day (I have enough trouble keeping small objects on low tables when I walk by in a petticoat), but they are wonderful to play around in. And a super wide petticoat is almost as good.
For this dress, I gave myself four yards to work with.
This is not a circle skirt, so it is not as twirly as it might be, but it is going to be pretty darn fun to wear! The petticoat is about half of its final size, so the skirt will be even more poofy!
