My toddler's bathing suit was left wet in a plastic bag after swim class a few too many times. She's outgrown it and I wanted to pack it up for the baby. I've washed it twice now and hung dry and it still smells kind of yucky. Is there any hope for it or should I just call it done and toss it? I don't want to box it up and make everything smell bad! It's definitely my fault for forgetting it in the bag overnight several times.
