Armani Prive

Last but not least: Valentino.

We'll be talking about this red carpet for a long time.

Truly, one of a kind.

From Gucci to Michael Kors.

Models! Gowns! Oh, and movies!

It's spidey sense-sational! (Sorry.)

The celebrity-filled red (uh, purple) carpet featured dozens of dazzling looks — and some genius Marvel-inspired accessories.

The Duchess of Cambridge attended the National Portrait Gallery Gala on Tuesday evening, along with Alexa Chung, Kate Moss and Victoria Beckham.

In addition to bows, celebrity chose lots of sparkle to kick off awards season.

An excellent way to bring the holiday season into the new year.

These ladies brought the high fashion drama, the Old Hollywood elegance and everything in between.

A final dispatch from the shows, including Maison Margiela, Alexandre Vauthier, Guo Pei and more.

From jumpsuits to cutouts to head-to-toe sequins, see which stars came out on top, sartorially speaking.

The moral of the story? Don't hug it out too hard while you're wearing couture.

Texture-mixing and just the right proportions made it work.

Kerry Washington and Lady Gaga notwithstanding.

The bride wore not one, but two custom Armani gowns on the second weekend of her wedding to Grace Kelly's grandson.

Electric pink walls, iridescent dresses and larger-than-life feathered coats made for a true feast for the eyes.

We've tallied up which designers scored the most — and best — red carpet appearances.

And Diane Von Furstenberg hints at an IPO.
