Before marrying Prince William, Kate Middleton was a fashion icon of the noughties. One of her most iconic looks was in 2006 when she watched her fiancĂ© compete in a polo match with her sister Pippa Middleton. Kate wore a stunning letterbox red halterneck dress with a plunging neckline and chunky red wedges adorned with large red flowers. She completed the look with glam sunglasses, silver accessories, and a blow-dried hairstyle. Pippa also looked chic in an aquamarine sundress. The sisters’ fashion sense was reminiscent of 90s chic, with Kate’s feathery hair framing her face and natural makeup.
