Jennifer Lawrence once again didn't disappoint with her fashion, as she walked the red carpet at the premiere for 'X-Men: Days of Future Past' in New York City last night wearing a beautiful backless blue gown that would make even her character Mystique proud. 

JLaw joined the all-star cast of the new 'X-Men' feature -- including boyfriend Nicholas Hoult, Patrick Stewart, Michael Fassbender, Hugh Jackman, James McAvoy, Ellen Page, Shawn Ashmore and Peter Dinklage -- at the worldwide premiere to where they were greeted by screaming fans waiting to get a glimpse of the mutant superhero group.

The Academy Award-winning actress' appearance didn't go without a hitch, however: she almost tripped like she did at the Oscars. She didn't seemed phased by the mishap, which is why she continues to be everyone's favorite BFF.

'X-Men: Days of Future Past' opens in theaters on May 23.

Fans, what do you think of Jennifer's dress?
