Abstract: A brassierestrap adjustment system comprises a brassiere having a pair of horizontally spaced apart shoulder straps, the straps each having a series of vertically spaced apart apertures or loops where each of the apertures or loops in one of the straps forming a horizontally displaced pair of apertures or loops with a corresponding one of the apertures or loops of the other of the straps. A clasp is enabled for snap-action fastening through a selected pair of the holes or loops, or may be constructed as a simple link with opposing hook ends for grasping the loops. In this way, the straps may be drawn into an “X” shape for improved fit and concealment of the straps under an outer garment.
