Designer Spanx brand so these are designed to hug your body and shape nicely. There is an extra tummy control panel built in as shown in photos. There are several photos showing measurements. This is a typical Spanx type fabric that has a lot of stretch. They are labeled however I would think a someone wearing a medium to large in typical women’s sizing would be most comfortable in these depending on how tight you want them. So please see the measurements. Brand new with the tags on them.
