From Style Arc:
Women’s knit jumpsuit sewing pattern.
Boardroom to bar, work or weekend, this versatile jumpsuit pattern comes with pants or skirt and can be made with sleeves or sleeveless. This understated style has a "V" neck, tie belt and it is fitted to a comfortable and flattering silhouette. The "of the moment" wide leg sits on the ankle. The skirt is a pencil shape and sits just below the knee. Make it with 3/4 sleeves or for warmer days it works well sleeveless.
