Bare midriffs weren't the only flashes of skin celebrities displayed on red carpet at Monday night’s Met Gala. Our fashion favorites also favored another sexy trend: plunging necklines. Reese Witherspoon rocked a GLAM-pink Stella McCartney gown, Jessica Alba looked racy in a lacy Diane von Furstenberg, and Lea Michele wore a gold lame Altuzarra dress as she walked the red carpet holding hands with Dianna Agron, who wore custom Miu Miu. Zoe Saldana made a bold statement when she arrived with Michael Kors wearing a black-and-white paisley-print number made by the designer. Zooey Deschanel rounded it out with a low-cut Tommy Hilfiger gown.
