There are so many reasons why everyone so interested in fashion because it is important to the society. Fashions is keep getting stronger by generation because of the influence from all over the world and it is like a drug which everyone is addicted to it.
It seems that you are really interested in studying about the influence of fashion to teenagers. Now in days fashion in the teenage world is like the most important thing to them. I agree teens don't want to feel left out of fashion they want to be and have everything that everyone in the fashion world have. I have experienced so many situations when a low class teen can not adapt to a fashionable teenage group because they feel like they are not at their fashion level. While you do your research you should interview people from school,for example the newcomers to know their point of view on your topic because i notice people see them as low class people, I think it will really help you. I'm really interested on what they have to say. Hope to hear a lot more about your topic
