We have seen Michelle Obama wear many designers, but for the first time today she wore Calvin Klein.

This look was worn to the Nobel Peace Prize Award Ceremony, where President Barack Obama accepted the 2009 Nobel Peace Prize at the Oslo City Hall in Norway.

The First Lady wore a chartreuse laser cut velvet dress and laser cut velvet jacket from the Fall 2009, but her two piece were custom-made.

I love the look without the coat, in which she wears metallic kitten heels, a Nina Ricci cardigan *ducks* and a stunning necklace.

I know many of you hate her wearing cardigans at such formal event, so how do you feel about his look?
