Abstract: A brassiere having breast cups molded from a heat settable, thermoplastic fabric, such as polyester, of warp knit construction and including top, middle and bottom guide bar yarns. The bottom and/or middle guide bar yarns have a denier per filament of at least 10. The stitch construction is particularly selected so that the bottom and middle guide bars run in opposition to each other and each have an underlap length which extends between at least two wales. Preferably, the stitch configuration of the bottom guide bar should be 1-0/1-2 and the middle guide bar should be 1-2/1-0. Alternatively, a stitch configuration of 1-0/2-3 may be employed in the bottom guide bar and 2-3/1-0 in the middle guide bar. The top guide bar primarily controls the aesthetics of the fabric and preferably may have a stitch configuration of 1-0/2-3 or, alternatively, a stitch configuration of 1-0/3-4. The molded bra cups have excellent shape retention properties, especially after repeated washings.
