A disposable bra liner has three layers which before use are flat, and in use become cup-shaped. The first layer is an outermost layer, the second layer is a middle layer, and the third layer is an innermost layer. The outermost layer and the innermost layer have circular peripheries and are disk-shaped. The middle layer has a central body portion and a plurality of arms extending outwardly in a generally spiral pattern. At least the outermost layer and the innermost layer are attached together, securing the middle layer between them. Regions of the first and third layers located between the spiral arms, when in use, become folded so as to allow contouring of the liner to the body of the user.
