Pleated Drop Crotch TrousersDESCRIPTION ZIGGY CHEN 2023 24 Autumn Winter Collection. This drop crotch trouser is made of expressive velvet fabric, a fabric that was particularly eye catching in the Paris installation of the 23 24 AW collection. The fabric features a dark tone brown base color with a red striped pattern that is not overly assertive. For the base, the brand uses front two tuck and back one tuck trousers that are typically deployed.
