There's no FRow like an Oscar-nominated, siren style FRow - and Jessica Chastain is all that and then some. So you can imagine what a stir she caused when she showed up at the Saint Laurent show in Paris on Monday wearing red vintage YSL.
Whilst she didn't go for the grungy-gorgeousness like Hedi Slimane's army of girls doing that raunchy-rebellious-leather thing, Chastain's look was stunning. The low-cut, knee-length, wrap-around dress was statement enough. Love it.
