Lisa Blue’s Thursday runway show kicked off Mercedes-Benz Fashion Week Swim with a star-studded front row that included Karina Smirnoff, Brooke Burke, and Christina Milian. In the days and shows that followed, celebrities and socialites were omnipresent. After an energetic runway walk at Lisa Blue, Smirnoff hit the beach Friday afternoon with CoverGirl Dania Ramirez for Muscle Milk’s Pop-Up Fitness Retreat.

Over at the tents, Christina Milian debuted her collaboration with Nicolita as Wilmer Valderrama and Cheryl Burke looked on from the front row. Models Nicole Trunfio and Jessica Gomes showed up at Vitamin A by Amahlia Stevens.

On Saturday night, at Mara Hoffman, budding shoe designer Angela Simmons, who also attended Luli Fama and Rose by Vanessa Jean on Sunday, sat front row.
