Hallo,
Sorry, but I write in English...
With my fetishes I vote for petticoats! It's more feminine when you feel layers by your legs. Even if it's very hard to wear, but I'd like to try so many layers as I can.
For Nadine - petticoats are more comfortable from my point of view. But for biggest gowns better if you use reifrock, it's more easy for creating of volume. In this case I prefer petticoat over a crinoline for making a more soft silhouette of skirt.
