hot-or-not

Spotted: Leighton Meester on the red carpet in fashion-forward lace getup.

Not one to shy away from avant-garde pieces, the "Gossip Girl" starlet wore a Marchesa jumpsuit from the designer's Spring 2011 collection while attending the Harry Winston Court of Jewels recreation launch in New York City.

The jumpsuit, which featured sheer black lace, an aggressively plunging neckline, and an open back, left very little to the imagination.

Possibly as a form of rebellion from their über-preppy alter egos, the "Gossip Girl" ladies have recently been seen sporting the black lace trend in some scandalous styles.

Blake Lively wore this Elie Saab backless, black lace frock in October while Taylor Momsen sported thigh-high lace stockings in August.

Meester completed her lace look with a funky ball purse, black Nicholas Kirkwood heels, loosely pinned waves, and bold red lips.

She sings, she dances, she sheds pounds like its nobody's business... is there anything Jennifer Hudson can't do?

Er, yes. Like pull off this unflattering bodysuit. (Though, in all fairness, who can?)

The Oscar-winning actress made a rare style misstep as she arrived at the airport in Washington, D.C., on Nov. 10 in a pair of ribbed, purplish-blue leggings worn with a matching lace top along with ankle boots and oversized sunglasses.

Unfortunately, the clingy, onesie-style outfit did no favors for the Weight Watchers spokeswoman's newly slimmed-down figure, clinging to her sexy frame and creating a dreaded camel toe situation.

Oh well. On the plus side, we suppose it was a more comfortable flying outfit than, say, heel-less boots or a strait jacket dress.

Stars -- they really are just like us! Or, you know, the sloppier versions of us.

Too busy to shave? Check. (Step right up, Hilary Swank and Natalia Vodianova.)

Prone to the occasional fashion faux pas? Check. (Just ask Charlene Wittstock.)

But even we only wear the exact outfit two days in a row when we're, um, doing the walk of shame.

So what's Claudia Schiffer's excuse?

In a case of déjà vu, the stunning 40-year-old supermodel was busted wearing the same outfit -- dark blue jeans, a striped shirt under a pale green sweater, a brown belt, golden bangles, oversized sunglasses, and a black crossbody bag -- as she took her kids to school on Nov. 3 and Nov. 4, The Sun reports.

The outfit was chic, but does wearing it twice in a row mean the mother of three has hit a style rut? Or was it just laundry day?

Or maybe Schiffer's trying to promote her new cashmere line by wearing her sweaters... a lot?

Meanwhile, the same Balmain dress has been featured on six magazine covers... including one starring Schiffer!

It seems '80s icon Joan Collins just can't let go of the style from her "Dynasty" heyday.

While stepping out for dinner at Mr. Chow in Beverly Hills on Oct. 3, the 77-year-old actress sported a white dress and a matching quilted Chanel clutch paired with a blue-and-white, floral-print blazer accented with huge puffy shoulders.

While we have to say the actress looks absolutely amazing for her age, we're unsure about her throwback of an ensemble.

What do you think: Should Collins keep the old-fashioned big-shoulder style going (she helped put it on the map, after all) or should she leave it in the past?

Although Kelly Osbourne has been off "Dancing With the Stars" for over a year, it looks like she's having a hard time letting go of the show's notoriously provocative ensembles.

On Nov. 1, Osbourne -- who placed third on season 9 of the dancing competition -- came out to celebrate the 200th episode of the series wearing a revealing Marchesa black cocktail dress that featured appliqué lace-covered cutouts at the neck, sides, and crotch as well as X-shaped chiffon draping on the front and back.

While we get that Osbourne is proud of her once-again svelte figure, we're unsure if this was the way to go about showing it off.

But we want to know what you think: Does Osbourne's frock deserve a standing ovation, or should it cha-cha its way back to the "DWTS" costume closet?
