This is Sara from J. Jill. Thank you for your question!
Our Cotton Jersey Knit Drawstring Skirt is designed to fall to knee length; however, it may fit differently depending on your height and body shape. Each size of this skirt is a different length. It may help you to know that our Misses size Medium (10/12) has a length of 20”.
If you need the length measurement on a specific size, you can contact our customer service agents, who can be reached by phone, email or chat and would be happy to provide you with additional measurements. To get started, click on the Contact Us link located in the bottom left corner of jjill.com.
