A breast support garment. The garment comprises a right fabric panel for overlying the woman's right breast when worn, a left fabric panel for overlying the woman's left breast when worn, the right and the left panels having a relatively flat configuration when the garment is not worn, a first variable-length material strip attached to the right panel beginning at a region between the breasts and extending along a lower region of the right breast when the support garment is worn, a second variable-length material strip attached to the left panel beginning at the region between the breasts and extending along a lower region of the left breast when the garment is worn and the first and second material strips expanding when the garment is worn to allow the wearer's breasts to be received within cups formed in the right and left panels and further for providing lifting and upwardly directed forces on the right and left breasts as the first and second material strips attempt to return to their relaxed state.
