I just use bikini bottoms for her that are pretty tight. Sometimes I put a cloth diaper cover (like you use for prefolds) over the bathing suit bottoms, then her swimsuit.

I use Charlie Banana swim diapers and I don't use her swimsuit bottoms.

I use Finis cloth swim diapers, usually over a Little Swimmers disposable because I am terrified of having an accident in our club pool and being the reason it gets shut down for hours on a hot summer afternoon. The difference between the reusable swim diaper and bikini bottoms is that the swim diaper fits tighter around the legs and waist to contain any poop, and is thicker so even liquid poops aren't likely to get into the pool. You still have to check often to make sure your little one hasn't pooped, but the reusable diapers will contain an accident. Little Swimmers alone will not, and if your baby's swimsuit isn't thick enough or tight enough, you'll have poop in the pool. Most of the time I don't put another swimsuit bottom on my daughter, but if the pool is really cold, another layer can help to keep her body temperature up. My sister is an infant swim instructor and has shared all this stuff with me, for what it is worth. At the private swim school she works at, they only have to shut the pool down for 30 minutes if they have a fecal accident, but in our club pool in my neighborhood, it can be shut down for 4 hours or more--so I am super careful with my 3 1/2 month old in the water. I wish other parents were too!
