Marc Jacobs and Char Defrancesco Get Married in Lavish New York Wedding

Marc Jacobs got hitched to his longtime partner Saturday night, and a ton of celebs were on hand to celebrate.

The 55-year-old fashion designer tied the knot in NYC with Char Defrancesco ... a former model who is now a candlemaker.

The event was a spectacle ... Marc and Char arrived at The Grill, where they had their lavish wedding reception, with Char wearing a crushed green velvet coat and bowtie.

As for the guest list ... check it out -- Anna Wintour, Naomi Campbell, Bella and Gigi Hadid, Bette Midler, Kate Moss, Lil' Kim, Rita Ora, Kaia Gerber and Emily Ratajkowski to name a few. Guests scored customized vape pens as party favors.

Marc and Char met 3 years ago and got engaged in April 2018. Jacobs proposed to DeFrancesco ... at a Chipotle restaurant. When it comes to fast food, both Marc and Char say Chipotle is their jam.

When he proposed, he organized a flash mob of dancers to perform Prince's song, "Kiss."

Marc was smart ... he got married the day after Char's 37th birthday, so he won't have to keep a bunch of dates in his head.
