Alva Baby swim diapers - set of 2

One diaper was worn once, but both turned out to be too snug for my baby. Sizing is considered ONE SIZE. See 2nd to last photo for sizing measurements or see below: One size swim diapers can fit baby 0-2 years, suitable weight: S(10-18lbs/4.5-8kg), M(18-30lbs/8-13.5kg), L(30-40lbs/13.5-18kg). (S, M, L REFERS TO USING THE CORRESPONDING SNAPS ON THE DIAPER!)
