Natalie Portman [1] has become a maternity style expert [2]. As challenging as it can be to dress a growing belly, Natalie has managed to pull it off on the red carpet. From the marigold Prada gown [3] she wore at the Golden Globes to the cream-colored Dior [4] number she debuted at the SAG Awards, Natalie has been putting a very elegant spin on maternity style. For the Oscar Nominee's Luncheon, the Jackie actress showed us all how to rock a little black dress while pregnant.

Not only was her look classic, but it's also affordable. The design is from Topshop [5] and was only $65. The dress was custom-tailored for the actress, and she paired the look with a matching belt and flats from Christian Dior. The chic, simple ensemble is easy to re-create, so read on to get inspired before shopping similar options ahead.
