When you look at what teenagers and kids have been wearing over the last couple of decades, they’ve usually conformed to what their peers wear so that they fit in and look good in front of their friends. But what I think has been changing is that the clothing styles of their groups has more and more imitated the clothing style set in other areas of the world, thousands of kilometers away.
The look and style of kids in Manhattan, New York, and West-coast LA is the style worn by kids in Sydney Australia, New Zealand, London and Europe. There’s nothing wrong with this, but from a marketing perspective it means that you need to watch what’s happening further from home. As global fashion trends become the dominant ones in areas that previously has more local input, marketing ideas and info is best found on Youtube, in Blogs and all the sources available on the internet that aren’t country specific. The research that you should do ( as mentioned in shop mannequins ) can in fact be largely handled on the internet.
