    Swim bottoms

    I only gave 4 ⭐ at this time as I haven't tried them in the water yet! The material and quality feels top notch. They are comfortable as well, I am expecting them to be great once wet as well. One thing to note is that I bought a small since that's the size of underwear that I wear, but had to exchange for a medium.
