All of Blake Lively's Met Gala looks, ranked from least to most iconic

The theme for the night was "American Woman: Fashioning a National Identity."

Lively stood out among other celebrities wearing floor-length gowns in this short look, which she paired with glittery black shoes and Lorraine Schwartz jewelry. Although the outfit was pretty, it wasn't as eye-catching as other Met Gala looks the actor has worn. 

Lively made her debut at the "Superheroes: Fashion and Fantasy" ball in a classic mermaid-style dress designed with feathers on the skirt. She coordinated the dress with black gloves and diamond bracelets. 

Lively arrived at the gala in a strapless gray-and-black Gucci gown. The dress had tiers of silk fabric and metallic beading across the hips. She completed her look with statement diamond earrings. 

Lively paired her outfit with simple gold heels at the "The Model as Muse: Embodying Fashion" gala. Her choice of understated accessories made it so all the attention was on the sheer sleeve, thigh-high slit, and plunging neckline design of the dress. 

The same year that Lively became the face of Chanel, she attended the "Alexander McQueen: Savage Beauty"-themed event in a gown from the brand's Fall 2009 Haute Couture collection.

Half of Lively's "naked" dress was embellished with silver flowers, and the other half was a long draped fabric panel. 

The actor arrived at the "Charles James: Beyond Fashion" exhibit in a floor-length gown covered in sequins. At the event, Lively told People that her outfit was an example of how much she loves dramatic trains. 

"I love a train, but then when I get on these stairs, I'm like, 'Why am I wearing a train?'" she said.

The red jewelry Lively wore coordinated with the pink color of the dress.

Lively looked ethereal in the pink-and-red dress. It had a thigh-high slit that was covered by a sheer fabric, so you could still see her leg peeking through. 

She was pregnant with her second child when she walked the red carpet but hadn't made the news public yet.

The train of Lively dress at the "Rei Kawakubo/Comme des Garçons: Art of the In-Between"-themed event was designed with four different shades of blue feathers. She completed her look with sapphire and gold jewelry. 

Lively's Versace gown for the "Heavenly Bodies: Fashion and the Catholic Imagination"-themed event took more than 600 hours to make.

The ornate ruby-and-gold gown was designed with a jewel-encrusted corset. She then accessorized the dramatic look with a spiked headpiece, Christian Louboutin shoes, and Lorraine Schwartz jewelry.

The actor, who was a co-chair for the 2022 event alongside husband Ryan Reynolds, arrived at the Metropolitan Museum of Art in a custom Versace look that changed from bronze to green to mirror the oxidation of the famous New York City landmark. The tulle dress was embroidered with crystal and metallic leather and tri-tone copper foil. 

When Lively arrived, the dress had an oversized copper bow at the hip leading into a long, dramatic train. The bow unraveled as she walked along the red carpet to reveal the green color. 

Lively told E! on the red carpet that the front of the dress was designed to emulate the architecture of the Empire State Building. She also said her Lorraine Schwartz crown was another accessory meant to mimic the Statue of Liberty. 

E!'s Zanna Roberts Rassi said the green side of the train was embroidered with a celestial map inspired by the same 12 zodiac constellations that are painted on the ceiling of Grand Central Terminal in New York City.
