Sanitary undergarment

A sanitary undergarment for preventing staining on an outer garment by a body fluid of a wearer, comprising:

• a fabric body comprising one or more layers for blocking flow of said body fluid through said fabric body, wherein the fabric body comprises:
• a front portion for covering a front part of a pelvic region of said wearer;
• and
• a rear portion for covering a rear part of said pelvic region of the wearer, wherein lateral edges of said rear portion are connected to lateral edges of said front portion;
• a crotch portion for covering a crotch region of the wearer, comprising one or more of a first layer and a second layer, wherein said first layer is disposed across a mid region of said crotch portion and said second 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;
• the second layer of the crotch portion forming an elongated fabric patch comprising a pair of outer edges, wherein said pair of outer edges are folded inwardly over the first layer forming lateral edges of the crotch portion for creating flaps at said mid region of the crotch portion;
• a waist opening 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 blocks flow of the 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.
