Abstract: A fly shield for a garment such as, for example, a pair of jeans. The fly shield includes a material folded and stitched to form a mitered corner. The mitered corner is defined by a fly shield seam and the fly shield has an approximate trapezoid shape defining two approximate right angles, a first acute angle, and an obtuse angle. The fly shield seam extends towards a vertex of the obtuse angle; and the fly shield defines a bottom folded edge that extends between the vertex of the obtuse angle and a vertex of the first acute angle. The fly shield seam and the bottom folded edge intersect to form a second acute angle, which is a portion of the obtuse angle.
