Hillary Clinton and Angela Merkel joke about their mutual love of pantsuits

It's no secret Hillary Clinton loves a good pantsuit.

Clinton, who possesses them in virtually every color of the rainbow, has made suits her fashion uniform of choice during her time in the public eye. And so prior to yesterday's state dinner, German Chancellor Angela Merkel, who is herself a pantsuit fan, poked some gentle fun at the Secretary of State's wardrobe, via an unusual gift--taking care to tell Clinton that "you may take it in a playful mode."

When they met on Tuesday, Merkel presented Clinton with a framed copy of the Frankfurter Allgemeine newspaper featuring an Associated Press photo of the two leaders during the Secretary of State's visit to Germany this past April.

The photo was of Clinton and Merkel, in their signature pantsuits, captured from the waist down and featured the caption, "Which one is Merkel and which one is Clinton?" The following page of the paper revealed the full photo--which Merkel included on the back of the framed gift she presented to Clinton Tuesday.

Upon seeing the photo, Clinton, who has frequently joked about her love of pantsuits, hooted with laughter.
