Our favorite couple with about a foot height difference--Prince Felipe and Princess Letizia of Spain--stepped out in Madrid on Friday and participated in a little royal PDA. The princess clutched her prince's arm and it seems there was also some giggling. Letizia wore her favorite plum dress and ditched her flats for her platform pumps, while Felipe went for a gray pinstriped suit, a blue shirt and violet tie and brown shoes. That's right--no black! Check out some pictures of these stylish Spaniards being lovey-dovey and let us know which is your favorite.
