The composite topsheet includes a resilient three dimensional apertured formed film, a nonwoven web small scale apertures, and large scale apertures. The formed film is between the absorbent core and the body facing side. The formed film has a male side and a female side opposite the male side, and small scale apertures with a mesh count. The nonwoven web of fibers is between the formed film and the body facing side of the absorbent article. The large scale apertures extend through the nonwoven web and the formed film. The large scale apertures have a mesh count which is less than the mesh count of the small scale apertures.
