The 2012 MTV Movie Awards were kind to Shailene Woodley, who took home the popcorn trophy on Sunday night for Best Breakthrough Performance in "The Descendants."

But something else, er, threatened to break through, as Woodley's plunging Stella McCartney double-breasted jumpsuit surrendered to gravity. The 20-year-old future herbalist (really!) paired her black ensemble with Stella McCartney heels and a fishtail braid, and kept her makeup minimal.

Sunday night's cleavage-baring look was a stark contrast from Shailene's Oscars 2012 dress, where she covered up a little too much (we think) in a stuffy white Valentino frock.

Did Shailene's jumpsuit jump the shark? Take a look below and weigh in! Also, be sure to check out Stylelist's picks for best- and worst-dressed.
