Michelle Obama chooses a Jason Wu dress again for Barack's farewell speech

President Obama delivered his farewell speech in Chicago on Tuesday, January 10 -- and as always, Michelle Obama was front row in the crowd, supporting him and cheering him on. Their daughter Malia was also in attendance (we don't know about you, but she really got the waterworks going for us), but Sasha was noticeably absent.

Near the end of his address to the nation, the president gave his family a teary-eyed "thank you," sweetly referring to Michelle as his "best friend."

Her one-shouldered, white gown in 2009 is perhaps most remembered and revered. Let's have a quick TBT moment:

It's safe to say we'll be watching Michelle's style long after she leaves the White House.
