Best Dressed, Showing an Unusually Large Amount of Skin: Gwyneth Paltrow

There’s little Gwyneth Paltrow could do to make it onto the lower (and far less glamorous) end of this list—she simply can do no wrong, most of the time, in our book. So when she showed up at the Michael Kors’s Golden Heart Gala on Oct. 15 in an angular black Michael Kors dress with cutouts, we just had to nod in silent appreciation.

Best Dressed, So Simple and Yet So Good: Sarah Jessica Parker

Here is a girl who likes to dress—and sometimes that means highly ferpitzed, piled on jewels, big hats, and ball gowns. And then there are moments like this: an architectural silver strapless Calvin Klein dress, Manolo Blahnik shoes, and Fred Leighton earrings. Somewhere a ball of tulle is taking a nap.

Best Dressed, on Tuesdays We Wear Pink: Michelle Obama

The first lady wore a neon pink bouclé dress and jacket by Michael Kors to the presidential debate on Tuesday night—which just happened to be the same exact shade of neon pink as Ann Romney’s dress. (Was it planned? For a second, the Twitterverse thought so, speculating that they chose the color as an act of support for National Breast Cancer Awareness Month). But a day later, the NBCA people emailed us with a denial: “We are unaware whether the Presidential Candidates’ wives wore pink to the Presidential debate in honor of National Breast Cancer Awareness Month.” But the first lady stole the show, channeling Jackie O. with a single strand of pearls and a shrunken jacket with bracelet-length sleeves.

Best Dressed, Lace Becomes Her: Karolina Kurkova

Usually the fashion crowd sticks to New York or Paris, but on Wednesday night, Boston was the place to be. The Museum of Fine Arts fêted the opening of its Mario Testino exhibition, “In Your Face and British Royal Portraits,” which attracted everyone from Anna Wintour to the model Karlie Kloss. But the standout of the evening was the stoic beauty Karolina Kurkova, who wore a short black dress with lace trim.

Best Dressed, Prim & Proper: Naomi Watts

The Impossible star looked lovely in a lavender and purple dress from Victoria Beckham and Christian Louboutin heels at “Take Home a Nude,” an auction to benefit the New York Academy of Art, at Sotheby’s on Thursday night.

Worst Dressed, Kim Kardashian Flashes Krack

Something seismic happened a few months ago, when Kim Kardashian subjected herself to the Kanye makeover treatment—clearing, presumably, vast stretches of fur and bandage dresses from her closet to appear more “high fashion” for her “fashion designer” boyfriend. The results have been largely problematic, with ensembles consisting of blacks and whites and strong shoulders and booties and experiments with no makeup. But then something like this happens and throws a wrench in everyone’s day. Kardashian went out for a stroll in Miami—wearing nothing but a bra and a transparent high-waisted skirt with nothing underneath.

Worst Dressed, Also With Nothing Underneath: Lea Michele

Another day, another Barbra Streisand attempt. The concept was, certainly, to emulate something from Dolce & Gabbana’s risk-taking and dramatic Spring runway—but the results were more than a little startling.
