So while not exactly insightful commentary, the official Obama delegation picture with the Pope struck me as odd.
All three ladies are dressed in black veils. All three ladies look very, very uncomfortable. I'm sure it was meant as a sign of respect for the Pope, but it is conspicuous because it looks like they are trying too hard.
But then I went back and looked: it seems to be the dress code for meeting the Pontiff at the Vatican. Black veil and knee-length black dress. I think it's particularly unflattering. (Then there's Robert Gibbs: that guy creeps me out.)
