There's no question that Gone Girl star Rosamund Pike has been killing it on the red carpet all awards season long, and that's largely in part thanks to her post-baby outlook on fashion. At the unveiling of Louis Vuitton’s Series 2 exhibition last night in Los Angeles, the star (who gave birth to her second child on Dec. 2), looked incredible in head-to-toe Louis Vuitton and dished on experimenting with style post-baby.

"It's a wonderfully freeing time right after you've given birth and you're a mom. It gives you an opportunity to really treat fashion as something fun because things don't exactly fit and your body is a different shape, which makes it a time to experiment," Pike tells InStyle. "Everything feels so fun and free for me at the moment. But there's really this juxtaposition where I'm at home feeding him, and then I put a dress on and am suddenly on the red carpet. It's surreal, to be honest. I'm just not thinking about myself and fashion that much. I'm sort of doing the red carpet and going back to the most important thing, which are my children."

As for her look at the event, Pike was loving it: "I realize this might become one of those iconic dresses. I think it's a really beautiful creation—it was the thing that caught my eye most in the Louis Vuitton collection," she says. "You've seen it in white in the ad campaign, and I'm wearing the blue version. I love the feeling of being covered up and protected. I'm not into revealing too much (Golden Globes gown aside), but I think there's something very nonchalant about this dress with its long sleeves, high neck, and short length."

The Best Actress nominee is gearing up for what will certainly be another fashion win at the Academy Awards, and we can't wait to see what she wears.
