The Golden Globes 2013 saw the stars work their black tie best, but earlier on in the day, the likes of Sienna Miller, Marion Cotillard, Amanda Seyfried, Jennifer Lawrence and Michelle Dockery warmed up for the fashion fest by showing off their tea party best at a BAFTAs bash in LA.

The party, which played host to the nominees for the BAFTAs ceremony on February 10, proved a seriously ladylike affair, as Sienna and Marion sported stunning floral dresses.

Giving a nod to British design, Marion's dress of choice was a jacquard Erdem number featuring a midnight-blue background and pink blossoms. A natural make-up look and simple undo complemented her girlie look.

While Sienna chose to champion Erdem at the Golden Globes, her daytime party look came courtesy of Valentino. A full-sleeve embroidered fit-and-flare dress and nude heels was a winning outfit for the new mum.

Top marks, ladies.
