“As a longtime ACOTAR reader and proud member of its fandom, I understand how deeply fans care about this world and every detail within it,” Nicole Tapscott, president of Knix said in a press release obtained by Woman’s World. “That passion shaped our approach from the beginning. We set out to create a collection that honors Sarah J. Maas’ storytelling while remaining unmistakably Knix in its design, innovation and purpose. This collection celebrates embracing your power, expressing yourself fully and feeling confident in your own skin, values that deeply connect ACOTAR and Knix.”
