Yesterday, the actress, who’s been relatively M.I.A. from red-carpet events this year, stepped out at the Lincoln Center to attend the New York City Ballet 2013 Fall Gala — in support of her husband, Benjamin Millepied, of course. Portman did not disappoint. She looked lovely and striking in a textured (i.e., pointy), tricolored strapless gown from Dior’s fall 2013 couture collection, and the bright pops of light blue and yellow gave her an extra-happy, mermaidlike glow. She wore her long hair down, accessorized with more Dior, and finished off her look with a dark smokey eye.
