A sewing machine presser foot is disclosed for use with a double needle sewing machine. The improved presser foot of this invention is designed for forming the rows of stitchings that secure a slide fastener or its chain closely along the marginal portions on each side of an opening in a garment, which rows of stitching are concealed from view when the fastener is closed, for which purpose there is provided a pair of relatively deep guide channels for accepting and guiding an element-free edge and a greater portion of each stringer tape in such a manner that the fastener assumes a combination L and inverted-L sectional configuration during the sewing operation.
