Despite those superglam getups she sports in Vogue's December issue, Angelina Jolie admits she's in a bit of a fashion rut.

"As Brad'll tell you -- and my kids -- apparently Mommy only wears black," says Brad Pitt's other half, who posed for Vogue's cover in a backless white number that reveals -- yup! -- a black lace-up corset.

But Jolie -- who wore a Neil Barrett cropped jacket, Helmut Lang pants, and Ferragamo flats for her interview -- says that turning to the dark side has nothing to do with being Goth or glam. It's just practical.

"I like to get up so every pair of pants goes with every top, every dress goes with every shoe. I've a very tiny closet," she tells the magazine.

"Brad's always laughing at me. Some days, yes, I have the nightgown that looks like a dress that I can sleep in and pick the kids up at school. And maybe take a meeting if I switch into heels."

Jolie definitely ups the wow factor in her Mario Testino photo shoot for Vogue.

In one shot, the elegant actress is seen pinning up her hair in a custom Colleen Atwood corset with lace trim, and a Club Monaco cashmere cardigan tied around her waist.

Another photo has her flaunting her mile-long legs in an Yves Saint Laurent satin tuxedo jacket, banded shorts, and patent leather sandals with rhinestone heels.

The regal star is also seen walking along a terrace of topiaries in a glorious Carolina Herrera fuchsia satin evening dress with bow details.

In the accompanying interview, Jolie dishes about her personal life, including what it's like being in a relationship with one of the world's sexiest guys.

"Well, he's a handsome man," she acknowledges before finding herself at a loss for words. "No, I think he's an extremely sexy -- extremely handsome and the most sexy...

"When I think about him, I just think of the man who's such a great friend and such an extraordinary father. And that's when I fall, you know, when I have my moments of getting -- whoarr! -- caught up in how much I love him... it's usually when I see him with the children."

Ah, the children.

The mother of Maddox, 9, Pax, 6, Zahara, 5, Shiloh, 4, and twins Vivienne and Knox, 2, says that she decided to do this summer's spy thriller "Salt" partly because she wanted to get back into shape after her double delivery.

"I was feeling very round and lovely and Mom-y, and I'd been living in a nightgown for a very, very long time," she explains. "Practicing the stunts is where you get your strength back."

Her follow-up film, "The Tourist" -- which arrives in theaters Dec. 10 -- gave Jolie the opportunity to wear fabulous clothes (including an original Charles James day dress) and spend time in gorgeous Venice with Pitt and the kids.

Speaking of kids, Jolie tells Vogue a story about daughter Shiloh that might stir up a mini scandal, but it has nothing to do with the tot's tomboy wardrobe.

"I am sure there's going to be some comment about this, which fortunately I will not read," she says before telling her tale.

"Shiloh found a dead bird, so she came in and said, 'Can I have a dead pet?' And I'm... 'Uh-uh, I don't think it's healthy, honey. I think they have to put him in a box,' and I had to run out to find, like, a taxidermy bird...

"I figured that I couldn't keep the actual dead bird from the yard, so I swayed her toward one that had been cleaned, at least."
