Jessica Chastain put her own spiced-up spin on the LBD last night for a screening of Lawless in NYC. The evening was hosted by Yves Saint Laurent and the Cinema Society; thus, Jessica came wearing the designer du jour. Did we mention she's also the face of the brand's newest fragrance, Manifesto? She paired her go-to black dress with black shoes, also by YSL, and colorful Tom Binns bracelets for contrast. Watch today's Fab Flash to see more! On Allison McNamara: H&M dress, Linea Pelle belt.
