The dress worn by Gaga on the set of House of Gucci differs from the original one worn by Reggiani. While they are both long-sleeved, photos from the wedding ceremony show the “black widow” wearing an unadorned, high-necked gown with a tapered waist. Meanwhile, Gaga’s features a high-low hem, a sweetheart neckline, embroidered details, and lace sleeves. (Manolo Blahnik’s Hangisi heels, which came out in the ’00s and were popularized by the Sex and the City film, are also period-inaccurate.) Like Gaga, though, her lace and scalloped cathedral veil was attached to a swept-back beehive updo. Both carried a large bouquet of white-and-pink flowers.
