Oscar de le Renta designed the stunning two-tone frock. And, despite the dress being a similar shade to the red carpet, Margot certainly didn't blend in.
The blonde bombshell stood out for all the right reasons as she cosied up to her co-star, Leonardo DiCaprio. Jel!
Margot's stunning ruby-red gown featured a high neckline, long sleeves and a dramatic floor length train.
A knee-length split offered a glimpse of Margot's perfect pins. And, although the dress covered up most of the Australian actress' flesh, her amazing curves were on full display, thanks to a sash around the waist.
Margot, 23, paired her gorgeous gown with a pair of gold 'So Kate' Christian Louboutin pumps and a matching gold ring.
The blonde actress sported a classic up-do, with a flowing fringe swept to one side.
Margot Robbie surely is one to look out for in 2014!
Wolf Of Wall Street is released on 17 January.
