Michelle Obama goes green in Calvin Klein to Nobel Peace Prize Awards

President Barack Obama delivered his Nobel Peace Prize lecture Thursday about fighting poverty and global warming, advocating human rights and striving for global peace --- a plan that ironically included fighting just wars.

And First Lady Michelle Obama also waved the US flag by wearing an outfit from the collection of American designer Calvin Klein. 

Michelle Obama wore a Calvin Klein Collection ensemble to the Oslo City Hall, where President Obama accepted the Nobel Peace Prize.

She combined a sulfite laser-cut velvet dress and jacket from Francisco Costa's fall collection for the house. This is the first time Obama has worn an outfit from Calvin Klein.

What do you think of her Nobel Prize ensemble?
