Final answer:
Teenagers often follow social norms and trends when it comes to buying clothes to fit in and feel accepted.
Step-by-step explanation:
When it comes to buying clothes, teenagers often follow social norms and trends. They want to fit in with their peers and feel accepted. This desire to conform and belong is particularly strong during the pre-teen and young teen years, as they are going through the process of identity formation and seeking validation from their peers.
For example, your younger sister may be buying clothes at the mall because she wants to wear what her friends are wearing, and because she believes that having certain clothing items will make her feel happier and more confident.
It's important to remember that this desire to fit in and conform is not static and can change over time. In high school and college, the main name brand clothing may vary, and the pressure to conform might shift to other aspects of life.
