Jessica Chastain Flaunts Cleavage In Plunging Red Dress (PHOTO)

Jessica Chastain showed off her famous figure in a vintage Yves Saint Laurent dress while attending the Saint Laurent Fall/Winter 2013 Ready-to-Wear fashion show in Paris on March 4.

The 35-year-old actress flaunted her cleavage (or middleboob?) in the red frock, which featured a plunging neckline. Pairing the dress with her trademark red hair, Chastain looked smokin' hot.

And apparently her new beau, Gian Luca Passi de Preposulo, thinks she's the most beautiful woman in the world. The couple was spotted out together for the first time, holding hands while grabbing dinner in the City of Lights.

Wait for it ... Awww.

Check out Jessica's sexy fashion week look below.
