From Seamwork:
With a chic, relaxed fit and an elasticized waist, Billie is the perfect jumpsuit for style and comfort. It features slightly tapered legs, a faced neckline, inserted pockets, a tie belt, and a keyhole opening at the back.
Sew it up in your choice of knit fabric, like a casual heathered jersey, a soft French terry, or a glamorous stretch velvet.
