       In our country there are many age groups that have different styles (风格)  of clothing. I prefer

comfortable clothes that are still very cool. I'm going to explair to you the kind of clothing each age group wears. Children at my age (10) prefer cool,comfortable clothing. For example, they wear T-shirts in many differernt colors. Teenagers who are older have their own style. They like more fashionable outfits (流行服饰). Then when they get to college they go back to comfortable clothing. I know a couple of girls in

college and most of them prefer sweaters and T-shirts.ln college they have long days and want to dress

comfortably. Finally, when they are adults they dress depending on (取决于)  their jobs. My mom is a

teacher and she wears khakis (卡其布) and sweaters. Some adults have business jobs,so they dress with nice shirts,ties,and suits (套装).I hope you enjoy learning about the clothing styles of American people.
