The stylish couple often attend events such as Wimbledon and the Royal Family Christmas concerts in elegant outfits. However, they have also dazzled in casual outfits. An old photo shows Catherine looking stunning in a turquoise long dress with a silk ribbon belt at the Boodles Boxing Ball in London. Catherine was photographed in a taxi with Pippa, who was on her way to Mahiki, a trendy London venue.

Catherine wore a stunning silver and gold satin midi dress with thin straps and a voluminous skirt. She rocked a voluminous hairstyle that has become her signature style. Pippa stunned in her Sarah Burton bridesmaid dress, but she also looked stunning in an emerald green ball gown at her wedding reception. The floor-length gown featured stylish Diamante detailing, complemented by high heels and a shiny silver bag.

While her tan may have been a little over the top, it matched the boldness of the event. Her plunging neckline added a daring edge to her look, and while it was eye-catching, it was perfect for the occasion. With Catherine wearing white for her second outfit, Pippa risked stealing the spotlight. Despite attending her sister's royal wedding, Pippa made a statement with her bold fashion choices. At the Boodles Boxing Ball, Pippa wore a simple yet stunning red silk gown with a plunging neckline and large floral detailing just below the bust.

The design looked like something you might see on the red carpet at a film festival or worn by a Bond girl. Although the dress had a daring neckline, Catherine had worn similar styles before her royal engagement. Since Pippa doesn’t have a royal title, she was free to express her style. Finally, Pippa looked stunning at the charity event, perfectly fitting the glamorous atmosphere.

A snap of the princess and Pippa at a polo match showed them enjoying the bubbles together, proving they are very approachable. Catherine looked chic in knee-high leather boots over skinny jeans, paired with a floral top and oversized coat, reflecting the fashion trend. In contrast, Pippa appeared poised in cork wedges and a smart navy dress, engaged in a serious conversation with her sister.
