Before Chanet Tisdel attended an October bridal show in Manhattan, the path to her May 2018 wedding was troubled by an imbalance of enthusiasm.

“I had been dragging my fiancé around to all these wedding shops and exhibits looking at all the girlie things, and he was just so unimpressed,” said Ms. Tisdel, 34, an executive assistant at Ralph Lauren in Manhattan. “He was just like: ‘I gave you the ring. I love you. I don’t understand why we have to do all this stuff.’”

Then Ms. Tisdel’s fiancé, Chauncey Kearney, had a change of heart. “While I was looking at flowers at the bridal show, he was like, ‘Hey, can you come here for a second?’” she recalled. “I walked over, and he showed me this invitation.”
