I am not going to the eras tour, but there’s nothing I love more than thematic dressing so hopefully this will help a Swiftie out! The skirt is so unique and fabulous! 100% silk on a taupe background with rainbow sequined squares. Skirt is marked as a size 14, but I would say it would more accurately fit a medium. Measurements taken flat: Waist: 14” Hips: 19”
