Blake Lively stepped out to celebrate the New York City premiere of her new film Another Simple Favor last night, arriving on the red carpet in a glamorous ice-blue gown by Tamara Ralph with semi-sheer lattice detailing on the bodice. The vibe? Bombshell.

The “Gossip Girl” alum stepped out looking her best at the Jazz at Lincoln Center while donning a blue gown with cutouts along the bodice that accentuated her figure.
