The president's daughter was pictured at Urbani Truffles in Manhattan where she enjoyed a decadent birthday meal with some of her relatives and friends.
Tiffany wore a daring white tuxedo dress for the occasion, braving the chilly October night with just a skin-tone camisole underneath.
She accessorized with a black handbag and wore a pair of towering black stilettos.
Marla Maples, Tiffany's mother, and her half-brother Donald Jr. appeared to be the only members of Team Trump who attended the festivities.
