Unless you've already developed your own unique style, you should start and then continue to experiment with your style. First, try something you wouldn't normally wear, like a color that you usually don't like. Then, step up the experimentation. For example, you could wear a mechanic's uniform and match it with accessories for a day. Your experiments may ultimately be a failure, but it is necessary to fail, even fail many times, on the path to becoming an icon. Go back to the list of words you wrote down that you wanted to describe your look. For example, the words may have been something like "futuristic" or "renaissance." Now, look for clothing and accessories that would fall into the category of "futuristic," "renaissance," or whatever your words may have been. The clothing doesn't have to be stereotypical of the words. It is all up to your interpretation. Fashion risks are very important when it comes to being a style icon. You can't be an influencer if you stay comfortable. Taking risks helps you grow, stay creative, and ultimately, they get you noticed. A couple fashion risks you could try are wearing all bright orange or turning pajamas into outwear. In the end, the fashion risk should stem from your own creativity. Fashion risks will never be something that is currently trendy. This isn't necessary, but it will help if you want to be truly unique when it comes to fashion. Making your own clothing will ensure that no one else in the world wears the same thing as you. Start designing your own clothes by drawing them or using a computer program. Then, learn how to sew your creations. If you get good at it, you could start making clothing for other people and even create your own clothing line. You shouldn't shop at just one place when developing your personal style. If you do, then you are essentially a model for a designer. Instead, shop at a wide variety of stores. Shop at thrift stores, high-end stores, and even department stores. Mix your fashion so the inspiration becomes untraceable. Many fashion icons have a recognizable accessory that makes them easily identifiable. For example, Jackie Kennedy Onassis could be identified by her signature gloves. Think about something that would pair well with your personal style. You could choose big sunglasses, a bow, or a unique ring. You could also choose to have quirky socks as your signature accessory. It's not necessary, but many fashion icons have a signature hairstyle that they've stuck with throughout the years. Betsey Johnson, Anna Wintour, Susy Menkes are a few examples. Your signature hair could be bright pink, shaved off, or very long.

Summary:
Experiment with your style. Put your list of words into action. Take risks. Learn to make clothing. Shop at a wide variety of stores. Choose a signature accessory. Pick a unique hairstyle.
