JUMPSUIT MUSTARD Fine CanvasDESCRIPTION O PROJECT 2023 Spring Summer Collection. This is the brand's first jumpsuit. 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 cotton linen canvas with a nep feel and just the right amount of firmness for a secure feel.
