High waisted trousers with two pleated back pockets. 

This pattern is not conventional. 

It was designed in 2018 by Mylène L'Orguilloux @milan_avjc with the first intention to provide alternatives for home sewers to better optimize fabric consumption and reduce the waste usually produced when cutting a garment. It therefore results in a rectangle jigsaw-like pattern where all the pieces fit together without producing any fabric scraps.
