This is such an interesting skirt it is made from a thicker, sturdy "crinoline" type fabric (i think linen) that keeps it's shape. It is double layered and you can barely see through it. I think it has lasted this long because of this fabric. I have never seen it in stores. I bought this years ago at an estate of a wealthy woman and she had quite a lot of older things.
I remember hand washing it and it came out great. I was considering letting the 24 waist out and keeping, but since it hasn't happened yet.
