British “It” fashion designer Pam Hogg performed two songs in a fetching gold lamé catsuit last week at Tribeca Grand’s Welcome to NY party. It was so crowded during her performance that longtime friend Debbie Harry stood on a chair to get a better look among the fashion crowd that included Derek Blasberg, Cory Bond, Jefferson Hack, Victoria Bartlett, the Misshapes and Amy Sacco. Harry was overheard telling event host Liz Vap that she “wouldn’t have missed the party for anything in the world.”
