President Obama is now a Nobel Laureate, but Michelle Obama's still a fashion plate, wearing Calvin Klein Collection for the first time.

For this morning's Nobel Peace Prize Award Ceremony in Oslo, Norway, the First Lady wore a sulfite laser cut velvet dress and matching jacket from the Fall 2009 Calvin Klein Collection by Francisco Costa.

Mrs. O's hair was in an elegant updo and her jewelry simple -- a floral trio on a ribbon in a complementary color. Once she removed the jacket, she added a cardigan -- yes, there's always a cardigan -- by Nina Ricci in the same bright chartreuse.

Mrs. Obama clearly loves her dress-jacket combos as well as this bright yellow-y green color that is not so far from her Isabel Toledo ensemble for Inauguration Day.

If it ain't broke...
