A shaped sanitary napkin. The sanitary napkin of this invention has an absorbent means, such as an absorbent core, and two flaps extending outwardly from the absorbent means. Each flap is associated with the absorbent means along a nonlinear line of juncture and each has two axes of flexibility. In use, the absorbent means is secured in the crotch of a panty and the flaps are secured about the elastic edges of the panty so that, when the panty is worn, the absorbent means is held adjacent the body while the flaps form a wall at each side of the absorbent means and seals against the body. Both the walls and the seals serve to prevent soiling of the body and clothing by menstrual fluid.
