Embodiments of the disclosed technology relate to wire-free push-up brassieres having the versatility to provide enhanced lift, support, and comfort across a range of breast sizes. A wire-free push-up brassiere disclosed herein includes a hinge that extends along a bottom edge of the padded portions of cups of the brassiere. The hinge may be a stabilizing channel formed between the bottom edge of the padded cup portions and a top edge of the cradle. The hinge may be formed of a stabilizing material that provides the hinge with both rigidity and flexibility. In particular, the stabilizing material may impart a rigidity to the hinge that reinforces the breast support provided by the cups, thereby enhancing the push-up characteristics of the brassiere. At the same time, the stabilizing material may have enough flexibility to allow the hinge to accommodate a range of breast sizes.
