Most leggings have a front rise seam which can potentially create the infamous "camel toe".
On some of our leggings we do a Diamond shaped crotch gusset. The seams are split to run through the sides and we also insert an extra layer of the same fabric to improve fit and comfort.
As you can see on the image below, we diverted the seams creating a diamond shaped stitching line and reversing improving fit, comfort and durability of the garments.
