The Piiru plissée skirt has a relaxed, A-line fit and it is made of dense recycled polyester in the Lokki pattern. The skirt has an elastic waistband.

The idea for the Lokki (seagull) pattern came to Maija Isola when she was looking at a window with a curtain drawn across it. The sun was shining, and the wide folds of the curtain formed wavy shadows on the fabric. Maija had a sudden inspiration: if a fabric is printed with waves, even a small piece of such fabric appears abundant, richly folded.
