Cara and Poppy Delevingne Hit Their Sister's Wedding in Style

Pippa Middleton showed off her famous curves in a Tabitha Webb peplum dress then added a fancy fascinator at Melissa Percy and Thomas Van Straubenzee's wedding in the UK in June. We love her black-and-white palette and think it's totally appropriate for a black-tie wedding. The fascinator is optional but would give you that British touch.
