Princess Stephanie (right) wears a jolly dress and a sort of bustier (?) at the Fight AIDS Monaco Gala for 2007. She's joined by her brother Prince Albert II (center) and his girlfriend, Charlene Wittstock, whom he married in 2011. The date was July 20, 2007. Princess Stephanie was born in 1965, so she turned 42 the year this photo was taken.
