Teri and her thong...
I have liked this woman since I saw her play Mrs. Santos on the west wing, she knows how to wear a first lady attire, and especially the episode Running Mates, Mrs. Santos is revealed to be wearing a red thong, with a lower back tattoo...very slutty, and yet sexy on a Presidential Candidate's wife. I wish she was our first lady, of course Michelle is pretty hot too, just needs to show what color her thong is...
P.S.
Here is the best picture I could find.
