Kendall and Joan Smalls kill it, while Halle is a ‘hell no!’

Between the swanky Vogue Foundation Gala and couture week in Paris, it’s been an expensive week in fashion for both the good and the bad.

The best worked high-designer like pros (indeed, three of them are models — deal with it), while the worst had extravagant aspirations that regrettably got them nowhere.

The hits:

Charlotte Casiraghi

Gucci’s newest and most ennobled ambassador of course wore the brand to the Vogue Foundation Gala in Paris.

Sleek, virgin white with just a bit of sex by way of cutouts — it’s a dress that desperately seeks a scandal.

Joan Smalls

For her turn down the Vogue Gala red carpet, the Puerto Rican beauty wore the very same Givenchy look Kendall Jenner wore on the runway.

We won’t say which model wore it better — actually, we will. Joan wore it better. She wins.

Karlie Kloss

Just when you think Kloss has committed to actually becoming Taylor Swift she goes and works something the singer never would: a slinky Saint Laurent slit dress paired with perfectly unhideous shoes.

Kendall Jenner

Walking couture for the first time clearly gave Kendall some Konfidence.

The model flaunted her newfangled ferociousness at the Vogue Gala in Balmain’s leather dress, serving “Xena: Warrior Princess” like the true fashion star of her tribe.

Tilda Swinton

Ms. Swinton’s love affair with designer Haider Ackermann is one of fashion’s most enduring and successful.

Stopping over in Berlin for the Roshi Porkar fashion show, the actress seamlessly mixed men’s and women’s pieces for a look that’s strong and soft, current and ageless, easy and utterly impeccable.

The misses:

Halle Berry

What is this silhouette you’ve adopted, Halle? Long-sleeved, skin-tight shiny dresses seem suffocating and are plainly unflattering. David Letterman could have told you this himself but he was probably too entranced by your cleavage ploy.

Please — get your head on straight, your hair redone and pedal yourself out of wash-up land.

Kristen Stewart

Proof Stewart’s common sense still matches her acting ability: She gets invited to Chanel Couture and shows up wearing Depends.

Nina Dobrev

Nice try Nina, but no. Atelier Versace is not in the cards for you. Stick to your Michael Kors.

Pink

You just know Giorgio was blasting “Get the Party Started” when he had the half-baked idea to invite Pink to Armani Privé.

She looks like a couture circus tent, and doesn’t even have the cotton candy hair.

Paris Hilton

For the LA launch party for her new single “Come Alive,” Hilton donned another gem from her avant-skank wardrobe.

Don’t look too long — you’ll lose brain cells.
