Sabrina and The Weird Sisters From Chilling Adventures of Sabrina What to wear: This could possibly be the most perfect Halloween look, weather for one, for a trio of friends or a group of four. To channel your inner witch, you'll need a red dress, platinum bob, and a black alice band. If you're girls are going as the Weird Sisters then you'll need black dresses with Victorian-inspired contrasting white cuffs and collar. To really nail this look, have one girl with long black pigtails, another with a red braided crown, and the third with cropped blonde finger waves. Magic! Image Source: Everett Collection
