Taylor Swift wore two looks, one refined and one cute, at today's 40 Principales Awards in Madrid. She walked the blue carpet wearing a white KaufmanFranco dress and Christian Louboutins and later changed into a red t-shirt and black shorts to sing at the event and work the press room. In addition to performing, Taylor also won the international artist award. She wrote on Twitter afterward, "Tonight was my first time at the 40 Principales Awards in Madrid and it was amazing. Thanks to the fans for the International Artist Award." Despite her two very modern outfits at the Spanish award show, she rocked a completely different look earlier this week — Taylor posed as Rapunzel for Annie Leibovitz's Disney Dream Portrait series.
