Abstract: The invention relates to a method of generating and using a virtual fitting room and to the corresponding system. According to the invention, computer means which are associated with a camera and display means are used to: photograph a garment and a user, such as to produce two-dimensional images (1, 2) and generate a series of positional measurements and outlines (C1, C2); generate a representation of a flat surface from the image of the garment (1) and superimpose said surface geometrically on the user's outline (C2); adapt the flat surface to the user's outline (C2) by performing mathematical simulations in relation to the garment; and display an image (3) of the user wearing the garment on the display means by superimposing the representative image of the user (2) with an image of the garment obtained from the two-dimensional image of the garment (1) and the adapted flat surface.
