While Pippa Middleton isn't exactly a royal, she is related to Kate Middleton and has style to match. While at Wimbledon in 2017, Pippa wore a blush-hued Self-Portrait dress that had a beige slip underneath. The dress featured lace cape sleeves, a white twill collar, and a grosgrain band at the waist. She styled the midi dress with a pair of gray stilettos and oversize sunglasses.
