Abstract: A woman's garment having seams which extend continuously from its upper edge to its lower edge to mould the upper body, said garment being characterized in that it has two lateral seams symmetrical in relation to the vertical plane of symmetry of the body, each seam following, downwardly, a path such that it crosses the breast, while passing substantially over the nipple region and while forming by a first contour a housing for the breast, and such that it crosses the side in order to be directed downwards and outwards towards the iliac crest then downwards and backwards to the level of the sacral promontory, and finally such that it crosses the gluteal muscles to extend at least as far as the gluteal fold while forming by a second contour, a housing for the buttock.The garment is one which moulds the upper body such as a one-piece bathing costume, an all-body tight garment, a leotard, or a blouse of the type closing between the legs.
