This is NOT a circle skirt, might be hard to see but compared to my other polka dot dress it isn't nearly as full...so with a petticoat it won't be full like in the pic they show. The Fabric is THICk and has a good stretch. i am a 12/14 dress size with a 40C/D bra and fits really well :) Nice sundress, just not a full skirt which I think is a huge part of why dresses like this qualify as "retro" IMHO
