A dress or skirt by french designer jean colonna, made from a single, very long tube of black polyester fabric with thin strips of elastic at both ends. This allows the garment to be worn fully extended, as a strapless dress, or folded onto itself to create a skirt. When in skirt form it has a kind of puffiness (this often seems to happen in my experience with double-faced garments, which this almost is (when worn that way)).

There is a version of the dress in a slightly larger size here.
