Blake Lively in Gucci Premiere

Blake Lively stunned in Gucci Premiere at the 2014 Met Gala.

The 'Gossip Girl' actress was undisputedly one of the best dressed stars of the night at the Metropolitan Museum of Art's Costume Institute Gala in New York City, where she walked the red carpet with her husband Ryan Reynolds.

The loved-up couple brought some old school Hollywood glamour to the event in their matching Gucci looks, with Ryan rocking a Gucci Made to Order midnight blue velvet one-button tuxedo.

But it was Blake, 27, who stole the show in her silk chiffon blush mermaid gown, custom-designed by the Italian fashion house, complete with a plunging neckline and gold paillette detailing.

Meanwhile, all eyes were on Sarah Jessica Parker as she made a real-life Carrie Bradshaw style entrance at the benefit gala in a breathtaking black and white Oscar de la Renta gown.

The fashionista took this year's classic white tie theme to heart, celebrating the opening of the new 'Charles James: Beyond Fashion' exhibition with her high-impact look, set off with white gloves and flowers woven into her hair.

Emma Stone was another standout on the night thanks to her modern take on the dress code.

The 'Amazing Spider-Man 2' actress looked effortlessly chic in a hot pink Thakoon two-piece which featured a thigh-high split.

Pink was the dominant colour palette on the night, with Reese Witherspoon and Kate Bosworth both clad in rose-coloured Stella McCartney dresses, British model Suki Waterhouse turning heads in a frilly peach Burberry princess number and Dita Von Teese sporting a fishtail, pastel-hued dress courtesy of Zac Posen.
