After joining volunteers for a mountain walk<\/a> with U.K.-based charity Mind Over Mountains<\/a> earlier this week, Princess Kate<\/a> made a surprise appearance<\/a> at an art exhibit. Wearing a sleek camel overcoat<\/a> and a black turtleneck sweater<\/a>, the Princess of Wales proved she doesn’t compromise her style, even when flying under the radar.<\/p>\n The Prince and Princess of Wales’s official Instagram account<\/a> posted a video montage of Kate’s private tour, with the caption, “My thanks to the team at The Arc in Winchester<\/a>. It was inspiring to see how they have placed creativity at the heart of the community and made art widely accessible.”<\/p>\n
