Harley has unkempt, rumpled hair. It will be easier to get this look if your hair is slightly curly or wavy. If you have straight hair, use a large curling iron to add loose waves to it. You can also spray your hair with a dry texturizing spray to help give it more volume. Don't worry above making it perfect or neat. Secure each pigtail with a hair tie. The pigtails need sit above your eyebrows and slightly behind your ears. Be sure to leave a few strands from your front hairline hanging loose. This is one of the key parts of Harley's look. If you have bangs, consider leaving them out completely. Use blue for the left pigtail and red or light pink for the right. Apply the hairspray from midway-down and be sure to work in small sections. Don't worry about making the color end in a straight line. A little unevenness would work great for Harley. This step can get messy. Wear an old shirt or drape a towel over your shoulders. Wearing plastic gloves might also help. Take a thin strand of hair from under your left pigtail. Wrap it around the base to hide the hair tie, then secure it with a bobby pin. Repeat the process for the right pigtail.  Try to finish wrapping the hair strands underneath the pigtails. You can also wrap a blue ribbon around your left pigtail, and a red ribbon around the right pigtail. Secure them with bobby pins or strips of double-sided tape. This depends on how messy your hair got during the previous steps and how voluminous it is to begin with. If your hair still looks too sleek, backcomb the pigtails from midway down. If your hair is still too thin, backcomb them all the way up to the base, where the hair ties are. If your hair is naturally curly or wavy, the colored hairspray might be enough to hold the style. If your hair is straight or smooth, consider spraying it with a lightweight hairspray to help hold the style.
