1880s New York’s most insane fancy ball costume

When Kate Feering Strong (below) received her invitation to Mrs. Alva Vanderbilt’s “fancy dress” ball, scheduled for March 26, 1883, she decided not to settle for a more traditional costume—like a Medieval princess or fairy tale character.

Nope, Miss Strong went as a cat—complete with an actual (dead) white feline as a head piece and a gown sewn with the body parts of real kitties.

“The overskirt was made entirely of white cats’ tails sewed on a dark background,” commented the New York Times.

The ball was arguably the most incredible social event of the year, and it also served as kind of a housewarming for the new Fifth Avenue Vanderbilt mansion.

“The bodice is formed of rows of white cats’ heads and the head-dress was a stiffened white cat’s skin, the head over the forehead of the wearer and the tail pendant behind. A blue ribbon with ‘Puss’ inscribed upon it, which hung a bell, worn around the neck completed the dress.”

Here are some of the other outrageous and ostentatious costumes, including the battery-powered “electric light,” worn by Mrs. Vanderbilt’s sister-in-law.

From wealthy socialite to women’s rights activist

When she was known as Alva Vanderbilt, she was one of the wealthiest women in New York City.

And as a young wife and mother in the 1870s and 1880s, Alva was determined to spend big bucks to secure a place for her family in the city’s stuffy, old money society run by Mrs. Caroline Astor.

To become part of the so-called Astor 400, she built a magnificent French renaissance mansion at Fifth Avenue and 52nd Street, modestly christened Petite Chateau (below).

She then threw a housewarming party in the form of a masquerade ball and invited 1,200 of New York’s richest residents, who feasted and danced while dressed as kings and queens. (Alva, right, as a “Venetian renaissance lady.”)

And when she couldn’t score a box seat at the Academy of Music on 14th Street, the city’s premier opera house at the time, she convinced other new rich New Yorkers to pitch in money to build the more opulent Metropolitan Opera House, which opened in 1883.

After finally breaking into formal society, she divorced her husband in 1895 and married another enormously rich man, Oliver H.P. Belmont.

For the next decade, she resumed life as a society matron, entertaining and building incredible mansions in New York and Newport, Rhode Island.

After Belmont died in 1908, however, Alva traded mansions and balls for activism. Instead of putting her money toward estates and entertaining, she began funding causes that advanced women’s rights.

That year, she founded the Political Equality Association and gave millions in support of the fight for suffrage both in the United States and in Great Britain.

Inspired by dedicated suffragists like Alice Paul and Emmeline Pankhurst, she helped launch the National Women’s Party, and she opened her mansion doors in New York City and Newport for rallies and events. (Above: 1912 Suffragist Parade, New York City.)

Her devotion to women’s rights expanded even after 1920. She helped support working women’s groups. The former wife of two famous capitalists even helped keep Socialist magazine the Masses financially viable.

She was living in France in 1932 when she suffered a stroke. At her funeral in early 1933, friends and family draped a banner across the coffin that read “failure is impossible,” per her instructions.

The woman who early in her life dedicated herself to becoming part of an American aristocracy made women’s rights around the world her lasting legacy.
