Size: XS Flat waist measurement: 35cm, inseam: approximately 70cm. The waist is elastic and stretchable, so it should fit those who usually wear S to M sizes. Worn only a few times, it's in beautiful condition overall as shown in the photos, so I think you can still wear it for a long time. Please check my profile before considering a purchase.
