This year, you can expect plenty of Justin Bieber and Hailey Baldwin costumes, but if you're thinking of going as Baldwin, there's one important question to answer: Are you blonde enough to pull it off? Because in order to do the leggy model justice — and so many other pop culture icons, for that matter — you have to get one thing right: the hair.
So, to make your life a little easier, we recommend starting your costume from the top down. Whether you're planning to buy a wig or just styling your own hair, we have all your Halloween hair inspiration ahead. These looks range from a Cher's waist-length black hair to a platinum Xtina with colored streaks, but each one is a Halloween classic.
