Olivia Wilde is on a quest to wear sharp-shouldered jackets.

The 'House' actress loves wearing fashionable, daring outfits so much she dreams about them while she sleeps and is on a mission to continually extend her wardrobe.

She said: "I even dream of buying a Balmain jacket with really sharp shoulders. If I can pull off that look, I will have succeeded, at least partially, in my quest.

"A cool leather jacket is my security blanket. No matter what I have on underneath, I feel more like myself when I'm wearing one."

The 25-year-old beauty also looks in department stores for quirky outerwear which she will mix with designer brands.

She explained to Lucky magazine: "Coats from H+M are inexpensive and usually have something extra going on - so even with a simple sheath dress, your outfit is still interesting.

"I own a lot of Helmut Lang. The pieces are practical in the sense that you can wear them every day, but they're not boring at all."
