Celebrities love Jenny Packham! The British designer launched her collection in 2003, which she followed up with a bridal line the following year, and her designs have been red carpet regulars ever since, appearing on Kate Middleton, Kate Winslet, Kerry Washington, Angelina Jolieand more. “I’m always flattered when someone chooses my designs,” Packham told InStyle.com at her spring 2012 fashion show in New York City. “I think women who like my dresses like to look feminine and classic but with modern elements.” The designer is known for her delicate eveningwear and sweet cocktail dresses with an emphasis on embellishment—a look clients like Jolie and Middleton adore. “I think if you want to emulate their style less is more,” Packham said of dressing the two style stars. “They’re about finding key pieces that have a perfect fit but still have an impact with subtle details and design techniques.” See who else loves wearing Packham’s designs in the gallery!
