If there's one thing Natalie Portman is (besides beautiful, talented, Oscar-nominated and pregnant!), it's eco- conscious.

Many remember when the 29-year-old 'Black Swan' star launched the now-shuttered vegan shoe line, Te Casan, in 2008. Currently, she sports a conflict-free diamond engagement ring.

Yesterday, much to the delight of fans looking to mimic her style, the Oscar nominee rocked an H&M look at a Vanity Fair party in Los Angeles.

Portman wore a white cotton frock from the retailer's new eco-friendly Conscious Collection to the mag's pre-Oscar event. The dress, which features beautiful long lace sleeves and a babydoll silhouette that's ideal for Portman's expectant figure, is made out of 100 percent recycled polyester, and retails for a very affordable $49.95.

Portman paired the piece with black and white bangles on both wrists, strappy metallic heels, and a sweet pregnancy glow. She is expecting her first child, reportedly a baby boy, with partner Benjamin Millepied in the coming months. Because of her approaching due date, Portman was unable to fly to the BAFTA ceremony in England recently to pick up her Best Actress trophy, but is expected to be a style sensation in designer maternity wear at this weekend's Oscars.
