The week's best celebrity style: Gwyneth Paltrow, Sienna Miller, Kristen Stewart and more

Tinseltown’s finest channeled their inner sirens this week, a few even opting for shades of crimson at A-list Hollywood events.

Former Disney kid Selena Gomez took to the red carpet for the L.A. premiere of her latest film, Ruderless, in a satin mini-dress by Christian Dior, while Lily Collins went for longer lengths (though no less sexy!) in a high-neck maxi gown in London for Love, Rosie.

Though these red looks fall on opposite ends of the length spectrum, they both gave us a hankering for some holiday dressing. The inspiration juices are flowing!

Gwyneth Paltrow and Jena Malone also topped our list, each putting her own spin on one of fashion’s biggest trends: the sheer overlay.
