The host's clothes are polyester. Polyester fabric: the advantages are good wrinkle resistance and shape retention, durable fastness, wrinkle resistance and no ironing. There is also easy deformation and mildew resistance after washing. Velvet fabric: good wear resistance and mildew resistance, light weight, suitable for winter clothing fabrics.
