We have a strong feeling these leggings are going to become a staple in your closet this Fall, which they SHOULD BE because hello....amazing. First off, the quality is unreal. They are nice and thick! With an ultra high waistband, they also hold everything in while forming to your body. They do have a little bit of stretch in them but if you are between sizes, we would suggest going up. These are made from a high quality, vegan leather material. Amy is a 10/12 and is wearing the large.
