The day before Britain’s royal wedding, the Other Kates — a group of three Washingtonians named variations of Catherine, all in their 40s, who have come here for the big day — sit in a Green Park pub and map out their wedding plan.

“See the dress. See the kiss,” says Cathy St. Denis, a Department of Transportation worker, outlining their priorities.

Much has been made of American women and their love for this wedding, this fairy tale, the adoration of a government system that America left behind centuries ago.

Kathryn Greenberg, who works in philanthropy in Washington, tries to explain.

“You come over to the U.K., and they actually have princesses. Real princesses,” Greenberg says. “And we don’t have to pay for them,” just enjoy them.

Greenberg remembers being woken by her mother and grandma to watch Diana Spencer get married on television: 6 a.m., at a bar, three generations of women.

“When I saw Princess Di’s dress, I wanted to be Princess Di’s dress,” Greenberg says.

“The way,” St. Denis adds, “she had to keep folding it and folding it into the carriage.”

“Let’s be honest,” says Katherine Miller, a communications consultant. “It’s like the World Cup for women.”
