Eva Green is literally too sexy for her shirt! A new poster for Dimension Films and Frank Miller's "Sin City: A Dame To Kill For," featuring Green was DISAPPROVED by US censorship group the MPAA.

Green dons a revealing white gown in the poster, captioned, "I've been especially bad." The MPAA rejected it "for nudity - curve of under breast and dark nipple/areola circle visible through sheer gown."

An industry source tells E! News these things "happen all the time."

"The movie will submit ads and the MPAA will ask for tweaks to be made," they said. "There's a compromise and that's it."

Studio execs will team up with the censorship group before the movie's release. Other more appropriate ads include Jessica Alba and Rosario Dawson.

Alba's dance instructor Jennifer "JJ" Johnson spoke about how the actress got in shape before reviving her sexy stripper role, Nancy Callahan.

"We just started to move to the music, and we were getting her used to the sensuality and moving around in heels in the beginning," she explained.

 "Then we started choreographing routines on her body. She would bring songs, I would bring songs - some were rock, some were sad, some were edgy, but they were all sexy." 

Johnson continued, "The secret to have a great bod and not having to kill yourself to look good is eating right," says Johnson. "That's a strong point of Jess's. She's motivated nutritionally, and she eats a balanced diet of salads and proteins. If you're eating right, that's more than half the battle." 

Another movie ad includes Mickey Rourke with the caption, "He doesn't mean any harm, but he causes plenty."

Fellow co-stars include Joseph Gordon-Levitt and Ray Liotta. The original "Sin City," based on Miller's book series, premiered in 2005 and was criticized for heavy violence.
