That said, some wore better outfits than others. Here's a look at the best and worst style moments of the fashion event.
Hailee Steinfeld stunned in silver and bows.

She posed ahead of the Tamara Ralph runway show in a long-sleeved gown from the designer.
Crafted from crystal-embellished lace, the dress had two cutouts, one at the chest and one at the waist, a tall slit in its skirt, a short train, and three bows attached to its bodice.
She wore it with stud diamond earrings and pointed black pumps.
Katy Perry's Balenciaga look left something to be desired.

She arrived in a blazer-style minidress, which had long sleeves and an off-the-shoulder neckline with a deep, V-shaped plunge.
While the dress itself had potential, it wasn't accessorized right. Perry wore no jewelry, carried no purse, and her hair was slicked back with only a single strand loose across her face.

The French brand designed her strapless, black velvet gown. Across its neckline, gold fringe accentuated its high shoulders.
To make the fashion moment even more dramatic, Cardi B briefly held a crow in her hand while posing on the venue's steps.
Lauren Sánchez Bezos kept her outfit so subdued that you might not have noticed her.

Not only did she wear large sunglasses that covered most of her face, but the recent bride also donned a modest, coat-style dress.
It had long sleeves, buttons down the front, and a high neckline. She wore it with black pumps and a Balenciaga clutch shaped like a coffee cup.
Kim Kardashian had a Barbie moment in pink.

After walking the Balenciaga runway as a model, Kardashian left the fashion show in a hot-pink set.
It included pink tights that covered her pumps and a form-fitting halter gown with a plunging neckline. She also sported black sunglasses.
Lisa Rinna's bright ensemble didn't have the same fun effect.

For the Balenciaga show, she wore an oversize jacket and baggy pants made from nylon-style fabric in a vibrant blue shade. She seemingly wore the jacket with nothing underneath.
Though the color worked for her, the outfit's shape overpowered the TV star.
Angela Bassett kept things simple but elegant.

She posed ahead of the Stéphane Rolland runway show in a flowing brown dress that was asymmetrical from top to bottom. It had a single sleeve on one side and a strap on the other, as well as layered ruffles of different lengths.
She complemented the dress perfectly with statement heels and a crystal-covered bracelet.
Patrick Schwarzenegger, however, could have benefited from accessories.

The actor wore a gray T-shirt and black trousers beneath a leather duster. Though the look was sleek and simple, it was also a bit lackluster for a couture event.
A sparkling brooch or a flashier chain would have improved the outfit.
