Washington, Apr 13 (ANI): Natalie Portman has revealed that her style has changed since she became a mother to her baby son Aleph, as she wants to look more mature.

The 30-year-old Oscar-wining actress welcomed Aleph into the world last June.

'I've been trying to look more like a lady recently. I used to be happy in a T-shirt and sweatpants, and now I feel like I want to make myself a little more grown-up - now that I'm a mom, Contactmusic quoted her as telling WWD.

The 'Black Swam' star also said that she loves vintage fashion because there's always a story behind the outfit.

'I feel like you are sort of stepping into history. It's really amazing to get the story of where a dress has been; you know that it has lived through many people's stories., she added. (ANI)
