This week, Stockholm-based fashion house Acne Studios is set to launch Acne Archive, a 48-hour online pop-up site. During the brief shopping window, a handpicked range of Acne Studios classics, show pieces and exclusive items from previous collections will be available for purchase at up to 75% off. The launch will take place October 26 at 9 AM EDT on Acne Archive and will be exclusive to U.S. customers, but look out for the archives to open to other regions in the near future.
