This is a DAMA product. It's a size S, but it might fit someone who usually wears a size M. Please refer to the measurements below. These pants have a slightly wide and very beautiful silhouette. The seam detail at the back of the knee creates a leg-lengthening effect. They have stretch. I don't see any stains, but since they are white, I apologize if I missed anything. Please understand that this is a used item. Flat measurements: Hip: Approximately 46 cm Hem width: Approximately 29 cm Inseam: Approximately 72 cm Color: White Pattern: Solid
