SI Swimsuit invaded Coney Island over the weekend with Nina Agdal and Hailey Clauson shooting for our super sexy Summer of Swim. The two-day shoot culminated on Saturday when Hailey marched as Queen Mermaid of the 34th annual Mermaid Parade.

Lucky for you guys, toward the end of the day, we ran into our old friend (and 2015 SI Swimsuit rookie) Ashley Smith, and that's when the real fun began. Ashley, dressed as a scantily clad (aka TOPLESS) mermaid, started an impromptu dance party with Hailey, and it was perhaps the sexiest part of the entire weekend.
