Brunet and her partner Pierre Brunet are considered[by whom?] groundbreakers in early pair skating. They are credited with creating mirror skating, and new jumps, lifts, and spins. At their first Olympic games, the 1924 Games in Chamonix, they performed more skills than any pair previously had. However, the judges thought they performed too many tricks, and they were awarded only the bronze. Other skaters took note though, and the Joly/Brunet style quickly became common in the sport. Joly and Brunet continued to perform skills previously unseen in pair skating. Joly was also among the first female skaters to wear a black dress to match her partner's outfit, rather than the traditional white dress.
Joly and Brunet also competed in individual events—Joly placed 5th and 11th at the 1924 and 1928 Olympics, respectively. She was also the French women's champion from 1921 to 1931.
Pierre and Andrée were married in 1929 (and thereafter competed under the name "Brunet" instead of her maiden name "Joly"). In 1936 they turned professional at toured Europe and Canada. In 1940 they emigrated to the United States. They became coaches, and trained future Olympic champions Carol Heiss and Scott Hamilton. They coached in New York, Illinois, and Michigan until retiring in 1979.
