NWT Aritzia Trix Dress Sz 12 (worn by Taylor Swift!) As seen on the music, style and everything icon, this is a fit-and-flare mini dress with bustier seaming details and a pleated skirt. It's cut from smooth, lightly structured fabric made with recycled materials and LENZING™ ECOVERO™ Viscose — responsibly sourced wood-based fibres produced through a process that reduces impact on forests, biodiversity and water supply.
