Tams, sashes, sporrans. They’re all worn with clothes made of tartan, a centuries-old woolen associated with Scotland. Woven in many patterns and colors, tartans—which are loomed plaids—were associated with districts and clans, thus suggesting identity. The world’s attention turned to tartans in 1822, when King George IV wore a tartan kilt on a visit North. The fabric became famous and has come to represent inclusivity, diversity, ritual, and rebellion. This exhibition tells the story of tartan with 300 objects. Couture use of the fabric is a highlight of the show, especially the dramatic creations of Vivienne Westwood and the incomparable Alexander McQueen. —Elena Clavarino
