Janie and Jack terrycloth coverup - size Small

This is the cutest swim romper. Made of towel material. My daughter wore this a handful of times after swim but a kid could wear it as an outfit really. There is very faint something, at the waist where the elastic pulls it in. It’s primarily only even visible when I stretch the waistband. In the pic of her wearing it that darker spot is a shadow. Not the mark.😂 Easy to wash. My daughter wore this at 5 and 6.
