Fashion Week is not normally the first event that comes to mind when one thinks of the perfect time to hold a political fund-raiser.

But perhaps that is because one is not Anna Wintour, the artistic director of Condé Nast and editor of American Vogue, publicly declared Hillary Clinton supporter (she wore a customized Hillary “Made for History” T-shirt to Marc Jacobs’s show during New York Fashion Week) and former high-profile fund-raiser for the Obama campaign.

Indeed, in the free evening between London and Milan fashion weeks, Ms. Wintour helped organize a pair of Clinton fund-raisers in the British capital, both featuring Chelsea Clinton, the candidate’s daughter, who is six months’ pregnant. They were a photo-and-cocktail reception hosted by the Washington native Elizabeth Pierson Sainty at the Stair Sainty art gallery in Mayfair, and a cocktail-dinner at the South Kensington home of Natalie Massenet, the American-born founder of Net-a-Porter.com and chairman of the British Fashion Council.

The designers Alber Elbaz, Christopher Bailey of Burberry and Tom Ford were among the couple of hundred guests paying $500 each for the gallery event ($1,000 including a photo with Chelsea Clinton) or $2,700 for the dinner. Mr. Elbaz, who cannot vote as he is not an American citizen, said he went to support his partner, Alex Koo, who is. Mr. Bailey, who is British, is a friend of Chelsea Clinton.
