Is it a skirt or a dress?

A couple of days ago I bought myself this cute piece at a discount. The price was so incredibly low for such a beautiful piece of clothing I thought I must be mad if I leave it. And for that price it was simply not worth the trouble making it.
To clear away all misunderstanding this piece was designed to be a dress. But while trying it and experimenting I saw that it could be worn as a skirt too. So versatile! The dress is constructed of several layers (flounces). The upper, last layer is not ruffled but straight and it ties up front with a thin strap.

But, by adding a sash or a thiny, thin belt it transforms into a lovely, flowy dress!

I know this is going to be my favourite piece this summer!
