What is a fashion house?

A fashion house is a company focused on one brand or designer. They design, make, and sell items. Products offered by them are always very luxurious, fashionable, and original. Also, fashion houses are well-known all over the world. They have an invaluable impact on creating fashion trends. For example, a very famous fashion house is Chanel. 

It is a brand created by French fashion designer Gabrielle Bonheur Chanel. She built her empire and revolutionized fashion by using new materials and styles. Also, Chanel launched gorgeous fragrances and cosmetics. They are famous all over the world even nowadays. After Mademoiselle Chanel's death, Karl Lagerfeld designed at the couture house. He restored the glory of the brand and helped it grow. Lagerfeld started incredible and unconventional fashion shows. They were an inspiration for people all over the world. In my opinion, Chanel is the only fashion house with such dignity and style all along.
