Lady Gaga gave shoppers at Bergdorf Goodman a thrill when she popped into the Fifth Avenue store on Wednesday wearing no pants. She glided in wearing only sheer crystallized pantyhose and a blazer with her signature uber-blond updo and glasses. “Everyone freaked out. The only thing big enough to draw eyes off of Hermes and Goyard bags is Gaga,” said one shopper. Gaga, who performed in Paris the night before, left with three bags full of Hermes and Chanel gifts and was overheard saying to two male companions, “I waited my whole life to be able to afford coming in here.”
