Plunging necklines and legs galore at the 2014 American Music Awards

It wasn’t the ladies of music who blew us away during last night’s red carpet at the American Music Awards.

The night belonged to the ladies of the big screen, especially Olivia Munn in a glittery gold lame Lanvin gown and Kate Beckinsale in classic white Kaufman Franco, who radiated glamour and stole the show in the event’s best trend: plunging necklines and sky-high slits.

Following suit: Both the younger Jenner sisters, Kendall and Kylie, chose floor-length numbers with slits up to there.

Elizabeth Banks kept it playful in a coral printed Peter Pilotto mini with deep V-neck.

Singers Jordin Sparks, who co-hosted the AMAs pre-show, and Fergie, who preformed her new solo “L.A. Love,” got in on the glam.Sparks arrived to the ceremony in a plunging sequinned Halston Heritage gown with ooh-la-la slit, while the Black Eye Peas frontwoman chose a sleek black floor-length number by Halston Heritage with halter neck, gold accents and – you know it – a slit revealing her toned legs.
