At an annual charity fund-raiser in October, Anna Wintour, the editor of Vogue, shared a table with the designer Michael Kors and Pete Buttigieg, then the mayor of South Bend, Ind., who wore one of his trademark navy suits.

The event was a benefit for God’s Love We Deliver, a nonprofit that began delivering meals to New Yorkers with AIDS in 1986 and has since expanded to serve other homebound people. On the second floor of Cipriani’s South Street location, guests bid for meals with the actor Neil Patrick Harris, watched the model Iman receive an award for her philanthropic efforts and heard a short speech from Mr. Buttigieg, who was also honored that evening. He said volunteers for the organization had offered sustenance “in substance and in soul.”

Sitting at a table near the stage was the theater producer Jordan Roth, who back in April held an event for Mr. Buttigieg’s presidential campaign at his home in the West Village, at up to $2,800 per head. Nearby was the board chairman of God’s Love, Terrence Meck, who had co-hosted an event for Mr. Buttigieg in Provincetown, Mass., just after the July 4 holiday. (Tickets for that ran upward of $1,000 per person.)
