How Mark Zuckerberg and Priscilla Chan transformed their style together over the years

For example, they kept their outfits simple on the red carpet for the 2014 Breakthrough Prize ceremony.

Zuckerberg wore a black tuxedo and satin tie, while Chan sported a sparkling, sleeveless dress in a deep shade of blue.

For a state dinner that year, Zuckerberg sported his usual black suit, tie, and dress shoes.

Chan, on the other hand, looked elegant in a vibrant red dress with a lace overlay. She paired the garment with a black clutch, simple sandals, and an updo hairstyle.

Zuckerberg continued attending events like the 2016 Axel Springer Awards in dark suits and white undershirts. Rather than accessorizing, he added only belts and dress shoes.

Chan, on the other hand, began sporting all-black ensembles that year. For the awards ceremony, she donned black leggings underneath a knit tunic and ankle-length boots.

For the annual Breakthrough Prize ceremony, Zuckerberg wore a black tuxedo with sharp, satin lapels and his signature tie.

Chan dazzled alongside him, wearing a black sleeveless dress beneath a glitter-covered fishnet overlay with a high neckline and long sleeves.

They both walked the Breakthrough Prize red carpet in black suit jackets, with Chan wearing hers over a solid black gown.

Zuckerberg swapped his usual necktie for a bow tie.

The couple attended the 2024 UFC 300 event in April while wearing casual yet cool outfits. Zuckerberg wore a white T-shirt with black jeans, and Chan donned a black blazer as a dress with sunglasses and a gold necklace for accessories.

Then, in May, Zuckerberg celebrated his birthday while wearing a graphic tee and gold chain.

Zuckerberg's fashion changes might have been strategic. Meta announced last summer that it was working to win over Gen Z.

The Facebook founder could have been doing the same by upping his style reputation.

Zuckerberg, who matched fellow billionaire Jeff Bezos at the event, wore a navy suit, white button-down shirt, and deep red tie.

Chan, however, made a high-fashion statement with a baby-blue Bottega Veneta set. She wore a $2,500 wool cardigan, a matching $2,800 skirt, and chunky pearl necklaces.
