Summer is heating up, and with it, celebrities are baring skin and wearing some of their boldest looks on the red carpet. From plunging necklines to vibrant colors, nothing's off limits.

Jessica Alba shimmered in (appropriately) gold at the Magnum Golden Butterfly Awards, while Natalie Portman chose a Christian Dior down with a artfully printed top half. Angelina Jolie and Angie Harmon both stunned in classic LBDs (Angelina in Atelier Versace and Angie in Azzaro), while Keri Russell stunned in a plunging J. Mendel gown, accessorized by a hot pink lip.

We're also seeing a lot of Antonio Berardi worn on the red carpet recently -- both Maria Sharapova and Michelle Monaghan rocked his looks this weekend. We're assuming this won't be the last we've seen of his designs.
