Pitt's tuxedo buttons and cufflinks were designed by Style of Jolie jewelry line with Robert Procop, reported People magazine.
Jolie, 38, had gifted the cufflinks to Pitt as a Christmas present.
"Brad's specially designed cufflinks were a gift from Angelina one year for Christmas," said Procop in a statement.
While Pitt wore a tuxedo at the Oscars, Jolie ditched her love for black by opting to dazzle in a shimmery Elie Saab Couture gown.
