A three-dimensional support frame for the linkage section (also known as “heart”) of bra cups for low-heart underwear is disclosed. The support frame comprises a body having a U-shaped support frame. The body of the support frame is made of a wide flat wire; wire surfaces of two vertical portions of the body of the support frame being correspondingly twisted outwardly at an angle with respect to a vertical axis, forming an anticlockwise angle of 15°-85° with respect to a vertical plane, and the twists starts at a position of the maximum radius of semicircular lower portion of the U shape. The twisted wire surfaces of the two vertical portions are of an arc-shaped structure which is curved outwardly, an outwardly curved portion with a maximum curvature being offset in a distance of 5 mm-50 mm with respect to midpoint of a bottom portion of the U-shaped support frame.
