When we ordinary citizens have wardrobe malfunctions, the best we can hope for is that a friend has a safety pin in her purse. Here's what happens among the celebrity elite:

At the 'Vanity Fair' Oscars after-party, Larry David gave Isla Fisher a "firm, hard hug" that snapped her dress strap. "I was exposed," she told Jimmy Fallon on 'Late Night' (weeknights, 12:37AM ET on NBC).

"But only at the 'Vanity Fair' party, the crowds parted and there appeared my fashion angel in the name of Tom Ford -- who had on him a cufflink, a wire coat hanger and a candlestick."

"He's like a fashion 'MacGyver'!" exclaimed the host. Evidently so. "He MacGyvered my strap back on, and I had a great night!" Fisher said. And who says the rich and famous are just like us?
