Our Stella McCartney invite for tomorrow is a little piece of metal, with plastic letters on one side. They're magnets that spell out "Stella," although it was a little hard for some editors to tell when they pulled theirs from the envelopes. "I thought it said ELLA," laughed an editor this morning, "And all I could think was that the show would have the Rihanna chorus of Umbrella going over and over again." It's okay, we told her. We thought ours said "Least 1."
