Fashion designers are those who make and design clothing. They select how new clothing styles will appear. Fashion designers make a wide variety of outfits. They create trousers, shirts, and gowns. They make hats and scarves. They even make handbags. The majority of the clothing they design is sold in shops. However, some fashion designers also work on a contract basis for companies that want to use their designs on products that they sell. In today's world of fast-changing fashions, it is necessary for fashion designers to keep up with the trends while still making sure that their clothes are affordable and suitable for all ages and sizes. It is their responsibility to make sure that what they come up with will be accepted by the public so that they will continue to buy their clothes. Clothing designs start as ideas within the mind of the designer. Then they are turned into sketches which may or may not become full-scale models. Finally, they are tested on test subjects (usually volunteers) to make sure that they fit properly, aren't itchy, don't hide any flaws, and feel comfortable to wear. If they pass this test, then they have found a market for their idea! The most common jobs for fashion designers are designing costumes for actors and musicians when they are performing, designing clothes for ad campaigns, and creating the looks for celebrities' weddings and special events. They may also work for fashion magazines or retailers.
