Catherinette is a special day for unmarried women in France. It is celebrated on November 25th and is named after Saint Catherine, the patron saint of unmarried women.
On this day, unmarried women over the age of 25 wear a yellow hat as a symbol of their single status. The hat is usually made of paper or fabric and decorated with ribbons and flowers. The tradition dates back to the 1800s when young women who reached the age of 25 and were still unmarried were considered "old maids." They would wear the yellow hat as a way of poking fun at themselves and showing that they were still happy and hopeful for finding love.
Nowadays, Catherinettes celebrations are more of a fun and lighthearted event, where unmarried women gather together to enjoy each other's company, drink champagne, and wear their fancy yellow hats. It's a way for them to celebrate their independence and embrace their single status.
In summary, catherinette is a special day in France for unmarried women over the age of 25 to wear a yellow hat, have fun with their friends, and celebrate their independence.
