Beige lines are featured on the sides. I used these as loungewear during my pregnancy. The fabric is similar to jersey material, so it doesn't wrinkle easily even after washing and drying, and the elastic waistband makes it comfortable. There are slits at the ankles, as shown in the third photo. I have two of the same item, so please comment if you'd like to purchase them together. Thank you for looking.
