Kate Upton Covers Up At Sports Illustrated Party (PHOTOS)

In a complete 180 from her 2014 Sports Illustrated Swimsuit back cover, Kate Upton decided to cover up her fab figure for a just-as-fabulous party on Thursday.

The model with the gravity-defying curves, covered up her body at the Sports Illustrated South Beach Soiree in Miami.

Wearing a black Zac Posen dress, the Vogue cover girl looked all grown up and (dare we say) more mature thanks to the simple cut of the dress which featured a v-neck, cap sleeves and a small slit.

In fact, the blond beauty was upstaged by her fellow 2014 Sports Illustrated Swimsuit cover girls, Lily Aldridge, Chrissy Teigen, and Nina Agdal, who rocked crop tops and skin-tight dresses.

Besides her Sports Illustrated stint, the model has been wearing more covered-up looks in recent photo shoots including a vampy spread she recently did for CR Fashion Book.
