Abstract

A garment with a backsheet (12), a bodyside liner (14) essentially coterminous with the backsheet (12) and forming a shape with a front waist section (18), a back waist section (20) and side sections connecting the front waist section (18) to the back waist section (20) and first and second flaps (30, 32) formed from or attached to bodyside liner (14). Flaps (30, 32) may have elastic members (40, 42) applied thereto respectively. Flaps (30, 32) may be folded inwardly and respective ends thereof may be bonded to bodyside liner (14) so that edges of flaps are directed toward a centerline (38) of the garment. The flaps (30, 32) may be attached to or formed from bodyside liner (14) along lines (34, 36) which are parallel to centerline (38) or which diverge from or converge toward centerline (38). Additionally, flaps (30, 38) may have varying width and be less than full length.
