Notes

Costumes in TV and films take an important role and it is a way of method for the director to use as a narrative and present in visual to tell the audience the story of the characters, for instance: what period the character is in? , what class division the character is in? etc. Costumes is also a way to tell the audiences the identity of the character through appearances.
In TV or films, when a star or actor wear clothes or a piece of jewellery which becomes iconic, people may started to follow what the star or actor was wearing in the film and it is one of the way for commercial as well.
Color choices of costumes is one of the significant things that need to consider as it may shows a specific or symbolic meanings to tell the audiences about the story. not only colors of the costumes is important in films or TV, but also texture and patterns need to be consider as well as for instance, if a character wears expensive garments which made with costly fabric, it shows wealth of the character. Also different time period reflects what styles, garments and fabric or patterns they wore.
There is a lot that can be said about a character in a movie by what they wear. The costume of a character alone can give you a hint about the period the film was set (in the 50s, 60s, 90s, or 2000s), the profession of the character (lawyer, doctor, clown, gangster), the financial status of the character (rich and exposed or poor and timid). We all remember the image of the costume designer in the Pixar smash hit The Incredibles. Yes some costume designers can be eccentric but they are an interracial part of the film production team.
