This pattern for casual trousers has been discontinued but can still be obtained. The legs are straight and designed to be rolled up and held in place with a buttoned tab on the inside. The waist sits at the natural waist - not below, as described on the envelope - and is finished with a facing, not a waistband.
My pair is a good fit, and I expect to enjoy wearing them. Other than omitting the map pockets, I made them exactly as designed. My fabric is a light khaki cotton from Sawyer Brook.
