Signature Style

1. Signature Style: Nicole Richie

No diaper bag for new mom Nicole Richie. Instead she sports her trusty Balenciaga Giant City bag, which goes for about $1,600 on Never leave home without one!

2. Signature Style: Jessica Alba

Whether she's in the dead of summer or the chill of winter, Jessica Alba always wears her trademark scarf—a chic accessory for simple dresses and classic coats alike.

3. Signature Style: Eva Longoria

She can verbally deny those pregnancy rumors all she wants, but the maxi dresses that Eva Longoria's wearing everywhere lately will keep raising the question: Is she, or isn't she? We can't speculate on that, but we can say that this petite housewife is showing women under 5'2'' that they, too, can rock this flowy look.

4. Signature Style: Fergie

They're skin tight, they don't breathe, and they show all the humps in her bump—they're Fergie's trademark rubber pants.

5. Signature Style: Lourdes

Lourdes Leon lives in her grubby black Converse, even when she's strolling the streets of NYC with a friend. The classic Chuck Taylor All Stars are $44.99 on Not too pricey for celebrity style!

6. Signature Style: Mariah Carey

If it weren't for new hubby Nick Cannon on her arm--and the fact that we know these shots were taken in 2007 and 2008--we'd think Mariah Carey was back in the early '90s. The singer's little white dress harkens back memories of her "Emotion" and "Dreamlover" days, but it's just proof that MC's style has never really changed. The diva also demonstrates that she's impervious to foot pain, since she can always be seen rocking sky-high stilettos.

7. Signature Style: Selena Gomez

Selena Gomez has already created a trademark look for her young self: skinny jeans (probably from Urban Outfitters), bone straight hair and unique footwear—though she reportedly has over twenty pairs of Converse in her closet.
