Sienna Miller Wears the Cutout Party Dress to Steam Up Your Summer Nights

Sienna Miller might have graduated to more simplistic street wear, but that doesn't mean she's left her inner wild child behind. For her latest red carpet appearance at the Tribeca Film Festival premiere of High-Rise, the actress selected a cutout Christopher Kane number from the Fall 2016 collection. But it wasn't just the slashes at her midriff and sides that brought sex appeal. The tomato-red midi was complete with extra straps and edgy pinned-on gems that were scattered about.

Sienna, who knows a thing or two about playing up a party dress, smartly slipped into silver ankle-strap heels and Tiffany & Co. jewels, leaving her bag at home. All the better reason to spin around and show off her glittering number.
