What a weekend! SI Swimsuit invaded Coney Island as Nina Agdal and Hailey Clauson joined photographer Ben Watts for the hottest photo shoot. And if that wasn't enough, our own Hailey took center stage as Queen Mermaid of the 34th annual Mermaid Parade. We documented all the craziness and have a bunch more surprises up our sleeves as part of SI's Summer of Swim.

But in the meantime, here's a little Instagram appetizer to hold you over!
