Abstract: The invention comprises a fastener mountable on a brassiere strap, either removably or permanently. A brassiere strap mounted on the fasteners can be removably affixed to a location on the posterior strap assembly and a location on the anterior cups of a brassiere. Use of the fasteners permits adjustment of the brassiere straps into a plurality of different arrangements, depending upon the shape, outfit and activity of the wearer. The brassiere straps and fasteners can be made of transparent or translucent materials which may be color tinted so as to appear virtually invisible against the wearer's skin. The brassiere straps can also be removed from a brassiere altogether.
