Signing boobs isn't only for rock stars. Or straight men.

"Social Climbers" author Beth Dunn, who happened to be wearing a Lilly Pulitzer dress designed by equestrian and former "Queer Eye" guy Carson Kressley, ran into Kressley on Thursday night at a private Devon Horse Show after-party at Siren Stables. Kressley, who now hosts "True Beauty," was happy to sign Dunn's dress.
