I am a size 26 waist, and I bought a medium thinking it would be a little bigger than a small. I usually wear a small in other swimsuits/surf brands but decided to size up because it is super cheeky. I am glad I did!! I think I could even wear a large and it would still be tiny. With that said, I love these SO much! They are so cute and have very little coverage. Perfect for tanning. Because they are tight, they are also suitable for swimming in the ocean without feeling like they will fall off!...
