Things out or in?

All kind trends about hobbies, music styles .hairstyles, clothing are changing every year. I think that peer pressure in those kind of things is very stupid because it is everyone`s own decision that what to wear or do. Music that everyone listens is pop. Singers who are popular among teens are like Ellie Coulding, Mikael Gabriel, etc. goth styles are like goth and heavy are specialty in 2015 year. Girls often use jeggings and squatting is very popular among girls. Nowdays hump working is in. Lads wear hoodies and dress shirts.
