I bought these right on rib pants from free people. Medium. Waist is stretchy and stretches comfortably to 16 inches across. I originally bought these in oatmeal but did a natural tye dye in plum (my favorite color if you look in my closet). Great shape. Didn’t end up but wearing a few times bc I wore my pink & green ones more. Now I’m moving in a month I have to down size Wrinkled from storage
