How do I change my look as a kid when I don't have money to spend on clothes?

Try wearing your clothes in different ways; something as simple as always turning up your collar can be a signature look. Try wearing clothes together that aren't usually worn together - wear dress shoes instead of your tennis shoes with jeans, for example. Roll up the sleeves of your shirts, wear them unbuttoned over a tee shirt. Turn up you pant legs. Ask family members if you can check out their wardrobes, vintage clothes can look great, or you might find a cool accessory you can wear. Use gel, mousse or hair spray to make your hair look different in a non-permanent and inexpensive way.
