“We’re both the same size. Why not be happy,” Ms. Clark said.

The couple married on May 27 before 250 guests at Ms. Clark’s grandmother’s home in Saddle River, N.J. Ms. Clark’s aunt, Marilyn C. Clark, a New Jersey Superior Court judge, officiated, while Ms. Pomerantz’s best friend, Kevin Leman, an executive producer for the “Ellen DeGeneres Show,” played master of ceremony.

“It’s going to be a wonderful wedding and not a backdrop for a murder,” he said, and gave a playful wink to Ms. Higgins Clark. “I always thought I would marry Lauren,” he continued, “just not like this.”

The ceremony included the reciting of “You Are My Sunshine” by Ms. Clark’s young brother David F. Clark and her cousin Courtney Morrison; a short reading from the Supreme Court Ruling of Obergefell v. Hodges; the brides’ original Tinder exchange; and deeply moving vows each had written to one another. During the cocktail hour, four synchronized swimmers performed routines in Ms. Higgins Clark’s pool.

“They are both so lovely,” said Ms. Higgins Clark, whose forthcoming novel, “I’ve Got My Eyes On You,” is dedicated to the brides. “And they look at each other so lovingly.”

Ms. Clark’s mother spoke similarly. “They are so well matched: Both are bright, talented, and sensitive. They understand each other,” said Mary Jane Behrends Clark. “I saw them looking at each other last night at the rehearsal dinner and thought, ‘They are really, really in love.’”
