Fashion month sees the industry's biggest names hit New York, Paris, London and Milan for the show-going, schmoozing and showing off their street style credentials.
With the biggest brands showing their new collections, editors, fashionistas and models, as well as actors and singers, are there in force.
Then, there's Couture Fashion Week where designers show their stunning couture collections. AW15 has seen the Christian Dior show bring in some A-listers who looked chic in checked mini dresses.
