It’s been 20 years since star-loved design house Badgley Mischka launched their brand. And founders Mark Badgley and James Mischka are celebrating the anniversary with an aptly star-studded ad campaign, shot by legendary photographer Annie Leibovitz. Images won’t appear in magazines until April, but we’re bringing you a sneak peek at the campaign, which gathers together Eva Longoria Parker, Carrie Underwood, Brooke Shields, Lauren Hutton and Anjelica Huston. So how do the women feel about taking part in the celebration? Underwood sums it up; “I love Badgley Mischka for not only making the most beautiful gowns,” she says in a statement, “but also for bringing together such strong, amazing women to celebrate 20 years of glamour and fashion. I am thrilled to be part of their special anniversary.”
