Being held in conjunction with London Fashion Week, American Vogue editor Anna Wintour, designer Tom Ford and actress Gwyneth Paltrow are hosting an Obama Victory Fund dinner in London next week, the Sunlight Foundation reports. The dinner, which will cost $40,000 to host and $15,000 to attend, will be held at the Mark's Club, a members-only club "based in a serene Mayfair townhouse that is discretely insulated from the hectic pace of the city outside," the organization's website boasts. Membership to the tony club costs up to $1,200 annually, and gentlemen must always wear a dark suit and tie. According to Sunlight's Party Time data, this will be the fourth time that Wintour has hosted an event for President Obama this year and a first for both Paltrow and Ford. Dinner will be served Sept. 19.
