When Boo wanders into the factory floor in Disney Pixar's Monsters, Inc., Mike and Sulley quickly discover she's anything but toxic â and one of Pixar's most heart-melting friendships begins. This charcoal wash sweater, designed at Truffle Towers, captures that magic with a sweet illustrated print of Boo in her monster disguise, finished with a bold lilac âBoo!â above. Soft, cosy and full of Monstropolis charm â because sometimes the smallest humans make the biggest impact.
