I live in Madrid so i will talk about fashion in Madrid and near by.
The most common clothes you will see are some Adidas leggings, Nike shoes and some other well known brand as the t-shirt. That is the main fashion with in the young population, but you can also find some other styles like e-boy. With the hairstyle we can see some palin straight long hair or you can see a lot of people with a quiff. But now its trendy to have a short like by the length of your shoulders.
Young people, in my opinion, are more keen in tattoos and body piercing than elderly persons. What do you think? do you agree?
