A feminine hygiene system for retaining a sanitary napkin on a users genitalia includes an undergarment that may be worn by a user such that the undergarment covers the users genitalia. The undergarment comprises an inner layer and an outer layer. A sanitary napkin is selectively positioned on the undergarment. The sanitary napkin is positioned on the inner layer such that the sanitary napkin may absorb menstrual fluids when the undergarment is worn by the user.
