Over the past two days, Pledis Entertainment has been updating the PRISTIN official Facebook with new photos. The photos are a new look into what the concept for their debut might be. Each girl has a photo with a different word, and a background to match the definition of that word. The words are: Mystery, Natural, Fly, Hot, Follow, Play!, Unique, Melody, Cool, and Little Lady. Check out the photos below to see their new looks!
