When you look as good as Sports Illustrated cover girls Chrissy Teigen, Lily Aldridge, and Nina Agdal did sporting their bikinis on this year's Swimsuit Issue, the effect is hard to top. But they debatably did just that when they arrived for the 50 Years of Swim bash in an array of sexy styles.
Taking the lead in a sheer and nude mini, Chrissy showed plenty of skin in her metallic-accented Philip Armstrong design. And she wasn't the only one! Nina took a color cue in her gown, and Lily raised the slit to new heights with cropped Thakoon  separates. Joining the cover girls, Anne V, Jessica Gomes, and Chanel Iman did their parts in a lacy column, red hot number, and plunging Rami Al Ali silver design, respectively. There's no question they all sizzled, but who looked hottest?
