I wore this for baby swimming lessons, which I started for postpartum weight loss. I bought a size L right after giving birth because my waist hadn't gone back to normal, but even after my body returned to its pre-pregnancy shape (I now wear size S or M pants), the elastic waistband still allowed me to wear it without any problems. There is some pilling on the bottom of the swimsuit and some deterioration on the inside, so I'm offering it at a low price. I recommend it for those who only plan to use it for a short period, such as for maternity swimming or baby swimming trial lessons!
