You don't see crinolines for Poser figures often, at least for long skirts.  I'd guess it's hard to make multiple layers of a long skirt follow the pose.  With a single layer, you can use body handles, but if there are several layers, it's hard to pose the skirt without the underlayers poking through.  Especially for sitting and the like. 

Two dresses come to mind, both at DAZ.  There's the Degas Ballerina dress, for V4, A4, etc.  It's a dress with a full ballet skirt, with at least two layers and textures that make it look like more.

And there's the old Morphing Cocktail Dress.  I think the skirt of that one has three layers.  It's for V3, but perhaps you could convert it.  Probably wouldn't be hard to fit just the skirt; it's not exactly form-fitting.

The tops don't look like what you want, but maybe you could combine the skirt from one item with the top from another.
