The claimed method for virtually selecting clothing is carried out on the basis of at least two photographs of the body of a subject dressed in an elastic template having reference markings. A computer may processes the markings, produce a three-dimensional mathematical model of the body of the subject, which is input into a database using an identification number pertaining to same. The database is accessible by a buyer, a seller and a clothing manufacturer. Standard-shape graphical elements are applied, in a regular pattern, to an elastic covering which is worn on the body, and the relationship between the elements is used as a basis for forming a three-dimensional model of the body.
