Jessica's Off to a Great Style Start This Week

We're not even two full days into the new week, but it's already easy to see which A-list star is ruling the red carpet this week: the beautiful and always well-dressed Jessica Chastain. Jetting around the world to promote the premiere of two of her latest movies, Chastain's red carpet premiere style has been garnering some much-deserved attention, thanks to her choice of stunning silhouettes, flattering hues, and plunging necklines that are equal parts sexy and sophisticated.

Despite the fact that the red-headed beauty has been extremely busy as of late — what with her many new movies, her campaign to become the next female superhero, and (how could we forget?) the debut of Chastain's new bangs — she's carved some time out of her packed schedule to flit from film festival to film festival to promote her latest projects. After hitting France for the Deauville American Film Festival and Canada for the 2014 Toronto International Film Festival, Chastain made her way on Sunday to the London premiere of Salome and Wilde Salome.

Wearing a flawless, tiered Erdem gown with a subtle floral pattern and a soft yellow hue, Chastain held onto the last shreds of summer in her pastel-colored ensemble.

Featuring side pockets and a down-to-her-bellybutton slit, the gown toes the line between downright sultry and tastefully covered up. And paired with a sleek, side-part bun and soft red lips, it's a ladylike way to give summer red-carpet style one last hurrah.

But overachiever that she is, Chastain didn't stop with just one gorgeous look. The star then attended the 2014 San Sebastian Film Festival in Spain on Monday, sporting an Oscar de la Renta resort number for the premiere of The Disappearance of Eleanor Rigby .

Showing off even more cleavage than before, Chastain's floral-trimmed, midi-length dress is a heavy dose of old-school glam. From the voluminous skirt and nearly off-the-shoulder cut to the retro curls and classic red lip, the looks screams elegance and glamour, while communicating major sex appeal with ease. So basically, it's a look that captures the essence of Jessica Chastain herself.
