For most people, the word "fashion" means "clothes". But people may ask the question, "What are in fashion?" And they use the adjective "fashionable" in the same way: "She was wearing a coat." "His shirt was really a fashionable color."
But of course there are fashions many things, not only in clothes. There are fashions in holidays, in restaurants, in films and books. There are fashions in school subjects, jobs…and in languages. Fashions as time goes. you look at pictures of people or things from the past, you will see that fashions have always changed. An English house of 1750 was different one of 1650. A fashionable man in 1780 looked very different from his grandson in 1850.
Today fashions change very quickly. We hear about things more quickly than in the past. Newspapers, radios, telephones and televisions send information from one country another in a few hours. New fashions mean that people will new things, so you see there is money in fashion.
