This fact serves to prove that clothes, which originated from the first coverings, were originally worn to allure. It was not the feeling of shame that caused resort to coverings and created clothes, but the very coverings provoked in time the feeling of shame.[A] Clothes owing their introduction to the irradiation of sex-attraction, fashion never disowned their origin. Fashion, says Bloch, bears witness of its intimate relationship to the vita sexualis, in that it always started from the ranks of courtesans and at the instance of opulent demi-mondaines. Gunther says: The demi-monde has always, since fashions are in existence, dictated them, in Rome, in Venice and now in Paris. Fashion has in two ways introduced a sensual element in dress. Either it renders conspicuous certain parts of the body and exaggerates their size, by the shape of the garment, its drapery and trimmings, or it leaves uncovered these parts to catch the eye. Both manoeuvers aim at the production of a sensual effect. The stretching of the skirt over the abdomen and legs in such a way that the outlines of the hips and thighs obtrude themselves upon the eye was surely invented by a Parisian demi-mondaine to serve sensuality. The corset, says Bloch, aims to render conspicuous and prominent the specific female organ, the bosom. It tries to effect an exciting contrast between the form of the bosom and the slimness of the waist, increased by tight lacing. At the same time, fashion dictates for a great number of occasions an ample nudity of this most alluring female organ.
