Xtina in Elie Saab

Christina Aguilera hit the red carpet this evening at Conde Nast’s 3rd annual fall fashion week kickoff party, Fashion Rocks, in a stunning Elie Saab gown. Aguilera, seen in the gown in both right and left images (although, yes, that's Sir Elton John with her in the image right) chose a black floor length gown from Saab’s couture collection. The gown features a square neckline on a structured bodice trimmed with flapper-esque beading. The lace skirt and train are sheer and feature scattered hand beading.
