Yes. It matters a lot - it makes a huge difference. "Looking okay" and "looking fantastic" aren't the same thing at all. When you wear beautiful clothes, you feel like a beautiful person - it makes you feel good, gives you confidence and strength! You can express your feelings, and be who you really are, instead of looking just like everyone else who is too afraid or too lazy to stand out! So if you feel like wearing polka dots, why would you wear stripes?!
