An ostomy body fitment for attaching an ostomy pouch to a persons body comprises a shapeable adhesive pad (44), and a shape defining member (46). In a first annular fixed shape zone (58), the shapeable pad is supported and shaped by the shape defining member (46). In a second central reshapeable zone (60), a portion of the adhesive pad (44) is unsupported by the shape defining member (46), and can be molded to fit an individuals stoma. A flexible flange (82) for removable adhesive attachment to an ostomy pouch has an attachment zone outside the periphery of the shape defining member (46), to reduce direct application of external forces.
