Fashion references to anything that is the current trend in look, dress up and accessories of a person.
The term "fashion" means clothing generally, and the study of it. Winter fashions trends vary considerably within a society according to age, man or woman, girls, kids, social class, generation, occupation and geography.
A fashion week is a modern industry event, lasting one week, which allows fashion designers, brands or houses to show and display their latest collections in runway shows and buyers to take a look at the latest trends. The most importantly is that it lets the industry know "what's in" and "what's out" for the 2014 seasons - fall fashion (autumn), winter, spring and summer.
The most prominent fashion weeks are in the fashion capitals of the world: New York, London, Milan and Paris. Each city host a special week twice a year, because there are two major trends seasons per year - Autumn/ Winter and Spring/ Summer season.
