Those Brant scamps are always finding their way into trouble. On Monday night, they got decked out in their finest — a sleeveless Dior satin tank for Peter, an electric-blue Dior leather blazer for Harry — and headed in from pastoral Connecticut to attend the CFDAs. The only problem? According to “Page Six,” they weren’t invited. “As soon as they were done having their picture taken, they were immediately escorted out,” a “spy” told the column. (Who knew fashion prom was crawling with spies?) Their rep countered, “[They] were invited but there was a ticket mix up at the door so they left. They did not walk the carpet.” Taking their dismissal lightly, the siblings made it to the Top of the Standard and Dior after-parties, which, as we all know, is where the fun stuff really happens. Like twerking contests.
