Wearing clothes that make you look professional is important. Wearing an unwashed, smelly T-shirt that has holes in it might make people think less of you, which is how people judge others. Have fun choosing clothes you like and make you look like you matter. Your hairstyle also says a lot about you. Long, spiked neon-green hair or a conservative, part-on-the-side old-fashioned hairstyle makes an impression on other people.
