Much was made--mostly by Oscar de la Renta --of the first lady wearing a European designer like Alexander McQueen for the state dinner between the U.S. and China last week .

"Mrs. Obama does look great. She should take that and do something. She could do a great good for our industry," de la Renta lamented to WWD , which went on to predict that Mrs. Obama would wear an American designer for Tuesday's State of the Union address.

And that she did, donning a Rachel Roy sheath . Her black and white ribbon was to honor Congresswoman Gabrielle Giffords.
