Anyone who’s ever seen J-Lo in *the* green Versace dress she wore to the 2000 Grammys knows that when it comes to red carpet fashion, a neckline can steal the show. This year, there’s been a huge resurgence of that infamous plunging neckline, and during last night’s MTV Movie Awards red carpet (the show airs tonight 8/7c), there was no one right way to play it. Stars like Charlize Theron and Brittany Snow dared to bare in the season’s hot hot hot plunging look, while others, like Farrah Abraham, chose more classically sexy strapless pieces. Halter necks also had a big night (thank you, Kendall Jenner), and other, more unique geometric shapes made Rebel Wilson and Katie Stevens stand out from the crowd. Read on to see who opted for what.
