Measurements taken with the item laid flat: Waist: Approximately 35 cm. Front rise: Approximately 22 cm. Back rise: Approximately 32 cm. 100% Polyester. The quality label has been marked with a marker. Please understand this before considering a purchase. The back waist has elastic, but it doesn't stretch much. It seems like you would tighten it with the drawstring in the front. We don't plan to wear it, so we'd be happy if someone who needs it would take it. Anonymous shipping.
