Massi used artwork by Jolie, 39, and Pitt's children and embroidered them on the train and veil.
Jolie and Pitt wed in a small chapel in a private ceremony attended by family and friends at Provence's Chateau Miraval.
Pitt, 50, told People the day was "relaxed and full of laughter".
"It was such a special day to share with our children and a very happy time for our family."
The couple's children took part in the wedding. Jolie walked the aisle with her eldest sons Maddox and Pax. Zahara and Vivienne threw flower petals. Shiloh and Knox served as ring bearers, a spokesman for the couple said.
A source told E! News: "Angie was given away by Maddox and Pax, and Knox helped with the rings ... Zahara, Shiloh and Vivienne had baskets of rose petals and other flowers they'd picked in the garden that morning and threw them in front of their mum and dad as they walked up the aisle."
