Unused and in beautiful condition. Includes a separate inner layer (see last photo). There's a cute orange Adidas logo stopper on the inside of the waistband to prevent the inner layer from peeking out. The flat lay photo shows it's about 37cm, but it's not a loose fit. The fabric is quite thick and well-made. It should fit perfectly for those who usually wear a size M. It's a very nice item. I bought it because I liked it, but I'm selling it because I've outgrown it. It's a simple and elegant dark navy, so it will be very useful. Great for everyday wear too! Will be compressed for shipping. Thank you for your understanding. Navy Adidas women's skirt, size M. - Brand: Adidas - Size: M - Color: Navy - Design: Skirt Thank you for looking.
