I vaguely recall the type of hat you seek. I don't know a site for them but surely it would not be hard to make a template around a bread/butter size plate from a cereal carton. Then sew a gathered crepe frill around the circumference, followed by a second overlapping frill. I also seem to remember the smaller size had a slit cut from outer edge towards the centre and the two sides overlapped slightly to form a very slight cone hat effect too. Does this help any?
