Jay Leno

During her first ever appearance on "The Tonight Show with Jay Leno" on Tuesday night, the First Lady stepped out in a shimmering gold sweater teamed with the same chic J.Crew pencil skirt she wore two-and-a-half years ago in London. While J.Crew has been a closet staple for the 48-year-old since her husband President Barack Obama took office in 2008, she has no problem pulling off high fashion labels.

In the fall of 2008, when the Snuggie was introduced in an infomercial, it was mocked by television hosts including Jay Leno and Ellen DeGeneres and went viral, garnering millions of viewings on YouTube and spawning hundreds of parody commercials.
