JUMPSUIT GREY SUMI ChambreyDESCRIPTION O PROJECT 2023 Spring Summer Collection. This is the first jumpsuit from this brand. This jumpsuit features a V neck neckline close to what was developed in the past season by the designer's signature brand JAN JAN VAN ESSCHE. A draw cord runs through the waist, and by squeezing the cord, the silhouette can change and gather. The fabric is made of chambray fabric, which is softer and lighter than the same type of cotton linen canvas.
