or Mackenzie Crocker, chats with friends and colleagues often turn to weddings. But Ms. Crocker has an unusually full bouquet of tidbits to add to the conversation. She expects to attend 18 wedding celebrations this year.

“Everyone and their mom in my life is getting married,” says Ms. Crocker, a 25-year-old from Conway, Ark. “It’s become a part of my personality at this point.”

The summer wedding season is upon us, and this time it’s coming down with the force of two tons of rice. Between nuptials delayed by the pandemic and those for recently engaged couples, this year could approach a record set in the 1980s for the number of marriages being celebrated. Ms. Crocker estimates more than half of her weekends over the past year featured a wedding, bridal shower or bachelorette party.
