Madewell Women's Skirt Size 6 Maroon Lace Asymmetrical Mini Faux Wrap Back Zip 
Fabric has no stretch. 
If fabric has no stretch please allow yourself some ease for comfort.
 
Measurements(laying flat): in pictures! 

Please remember, since it is pre-owned it's a good idea to review measurements, since previous washings could cause shrinkage. 
Any questions I am more than happy to help!
Happy shopping! Thanks for your support :)
