Giselle from Enchanted
Giselle is a character from the 2007 Disney film enchanted, and is played by Amy Adams. Enchanted follows Giselle, a princess who is banished by an evil queen and has to go from her animated world to the real world.
In one scene Giselle wears a poofy white wedding dress in the city. This can be recreated with a white wedding dress with poofy short sleeves, a white petticoat for volume, and a white ruffled skirt to layer under the dress that will show through the slit in the skirt. She pairs this with a silver necklace, tiara, and white satin gloves.
