The blonde bombshell hit the red carpet for the sequel to Fifty Shades of Grey. In the second chapter, Basinger stars as Elena Lincoln.
Co-star Dakota Johnson also made a fashion statement with a low cut dress as she posed with onscreen lover, Northern Irish actor Jamie Dornan.
While Fifty Shades of Grey made $85 million on its opening weekend in 2015, predictions for this weekend's sequel are expected to be half that.
The cast and attendees of the film then partied at a masquerade ball inspired by a scene in the new film.
