A brassiere back closure has an inelastic textile patch attached to the end of one of the brassiere wings and carries a plurality of transversely extending and longitudinally spaced rows each having at least two transversely spaced eyes on the back face. A flat body has an inner end attached to the end of the other of the wings, an opposite outer end, a front face at least partially overlapping at the outer end the back face of the patch, and a back face opposite the body front face. Respective plastic hooks generally complementary to and matable with the eyes are fixed to the body front face at the outer end so as to align with and interfit with the eyes. A transversely rigid bar on or forming part of the body prevents transverse relative movement of the hooks and bending of the body at the hooks.
