After seeing this picture, I let out an immediate "OH. MY. GOSH." It was very dramatic, very loud, I was very alone whilst doing it, but I don't care. Jessica Chastain looked stunning last night at the Harry Winston party last night, which was thrown in her honor, by the way. I cannot get over her adorable Jason Wu dress (Which was one of my favorites from his latest collection.), her Harry Winston jewels, her hair and her makeup. Everything is flawless. Don't mind me as I girl crush all over this. Okay. Great.
