I'm a big Fanning: Marc Jacobs with the young starlet backstage at his New York show
The Man On Fire star gave off a dainty air in the subdued patterned frock, which she paired with white and perspex sandals and a silver clutch bag.
She matched the muted number with a rather understated approach to her cosmetics - wearing her blonde hair out in a natural style and maintaining a fresh-faced complexion for the occasion.
The young star posed with Jacobs himself, who appeared to flout New York state laws by smoking a cigarette backstage.
Dakota also indulged in a photo op with director Sophia Coppola, who was handpicked to pose Marc Jacobs in one of his perfume advertisements back in 2002.

Rachel Zoe was also pictured at the event, posing up with Marc Jacobs, where he was again seen with a cigarette in his hand.
Material girls: Jacobs' show consisted of numerous unconventional uses of fabrics
The show itself comprised theatrical choreography which saw around 50 unworldly outfits mixing materials and turning conventions on their head.
Observers noted raincoats made from cellophane, fringed coats, fake crocodile for straight yellow or dark red skirts, sparkly turbans and loafers - he even put the models in strange, transparent cowboy boots.
Nylon, cellophane, organza, silicon and silk socks matched with golden high heels were just some of the materials he used, setting up a show to delight celebrity fans and industry fans alike.

The background, is similarly juvenile - it's monotone pastel pink compounding the innocence of the composition.
But then a large bottle of the scent, featuring it's signature rose-top has been placed provocatively in between the young starlet's legs.
The teenager clutches it as she tilts back lasciviously and stares intently into the camera.

New Yorker Jacobs admitted that his intention was to portray the young woman as a reimagination of the tragic character in Vladimir Nabokov's 1955 novel, Lolita, which tells the story of young girl's sexual relationship with a much older man, who becomes her step-father.
He told Women's Wear Daily: 'I’ve been a big fan of Dakota since the first time I saw her in a movie, and we made her a wardrobe in her size when she was 12, which was pretty incredible.
'When we were speaking about who to use in the ads, I had recently seen The Runaways...I knew she could be this contemporary Lolita, seductive yet sweet.'
Lolita reborn: Marc Jacobs admitted he intended Dakota's appearance in his perfume ad to be a reincarnation of the tragic character in Vladimir Nabokov's 1955 novel
The iconic novel tells the story of sexual predator Humbert Humbert and his exploitation of his 'Lolita' from the age of 12.
Ironically, this is the age at which Dakota first posed for the successful designer.
The pull of Jacobs is so strong that Fanning admitted she was: 'humbled by the offer and said yes immediately.'
