A sanitary undergarment for preventing staining on an outer garment by a body fluid of a wearer, comprising: a fabric body comprising: a front portion for covering a front part of a pelvic region of said wearer having a waist region; a rear portion for covering a rear part of said pelvic region of the wearer having a waist region, wherein lateral edges of said rear portion are connected to lateral edges of said front portion; said front portion and said rear portion of the fabric body comprising: a first fabric layer made of an absorbent material for absorbing the body fluid, wherein said first fabric layer comes in contact with the pelvic region of the wearer; a second laminate layer sandwiched between the first fabric layer and a third fabric layer, wherein said second laminate layer is made of a breathable fluid leak-proof material for preventing leakage of said absorbed body fluid to said third fabric layer; and the third fabric layer exposed to the outer garment of the wearer; a crotch portion for covering a crotch region of the wearer, comprising at least a fourth crotch layer and a fifth crotch layer, wherein said fourth crotch layer is disposed across a mid-region of said crotch portion and said fifth crotch layer comprising a first edge attached to a waist region of the front portion and a second edge attached to a waist region of the rear portion; and wherein said fourth crotch layer is made of an absorbing material for keeping the wearer dry on the inside, and said fifth crotch layer is made of an absorbing fluid leak-proof material and acts as a receiving pouch for excess body fluid; the said fifth crotch layer forming an elongated fabric patch comprising a pair of outer edges, wherein said pair of outer edges are folded inwardly over the fourth crotch layer thereby forming lateral edges of the crotch portion for creating flaps at said mid region of the crotch portion, whereby the said fifth crotch layer encapsulates the fourth crotch layer; a waist opening disposed adjacent the waist regions defined by an upper edge of the front portion and an upper edge of the rear portion; and thigh openings defined by a pair of lower edges of the front portion and a pair of lower edges of the rear portion, wherein said lower edges of the front portion and the rear portion are extended to cover inner thigh regions of the wearer; whereby the fabric body, having multiple layers of protection, blocks flow of body fluid of the wearer outside said sanitary undergarment and thereby prevents staining of said outer garment on said front part of the pelvic region, said rear part of the pelvic region, said crotch region, and said inner thigh regions of the wearer, and provides comfort to the wearer by allowing air permeability.
