Jessica Chastain Flashes The Good People Of New York

Are those your unmentionables showing Jessica Chastain?!?
The redhead had an extreme OOPS moment on the set of The Disappearance of Eleanor Rigby on Monday when her loose-fitting black dress blew up in the passing New York City breeze.
It took a while for Jessica to notice that her dress was lifted in the air, but once she did, she pulled down her garb and stopped giving everyone a private show.
Dying to know if Miz Chastain was wearing panties??? Find out…AFTER THE JUMP!
