Great petticoat. I debated medium or large (I typically wear an 8) and went with the large. It's fine, but the medium would have been fine, too. The petticoat provides perfect fullness for a felt poodle skirt, and the color (I went with lavender) is fun. The lining means that no scratchy crinoline is rubbing against my legs, and the top is smooth and invisible under clothes. Definitely recommend.
