The model wore her oh-so-chic frock as she attended a swanky bash at hot London nightspot Loulou's last night (16 September).
Her dress featured a peek-a-boo cut-out detail across the chest, fastened with two gold buttons. The body-hugging shape highlighted her slender silhouette while the high neckline kept things on the right side of sexy.
To complete her outfit, Rosie opted for strappy heels decorated with statement gold hardware and a metallic clutch.
And while we're used to seeing her sporting barely-there make-up, this time she added a touch of glamour with black feline eyeliner.
Perhaps she was inspired by the dramatic winged liner from her recent Elle magazine shoot?
