Marc by Marc Jacobs Denim Skirt Used item. This skirt is meant to be worn low-waisted, so the waist size isn't the most important factor. If you try to wear it at your natural waist, it will likely be too loose. It's designed to be worn lower on the hips. The size is indicated as 4. Length is approximately 42.5 cm. I loved this skirt and wore it often, but I no longer wear skirts, so I'm selling it. #MarcbyMarcJacobs
