The marketing strategy of Lang Wen (Lanvin) is dominated by boutique and fashion show. Since the creation of Langwen's "romantic house" store on Santa Ana street in Paris in 1889, more than 200 employees in the Lanvin store in Paris have been made up of six departments: Women's wear, men's wear, tailor-made suits, accessories, perfume and watches. The Haute Couture fashion of Lang Wen (Lanvin) has been sold to Japan, Hongkong and Taiwan, as well as New York, in addition to sales in France. Today, though Lanvin's advanced custom fashion business is over, there are still many clothing stores in many countries and regions such as France, Morocco, Britain, Russia, Switzerland, Turkey, Hongkong, Japan and Thailand.
