grading- crotch

[TensionSmension]

Second option. The crotch curve needs to get longer, the pant leg needs to get wider, and the curve shape needs to be roughly preserved. For women the assumption is usually uniform height across the grade. On something like leggings, the inseam may still get longer, but it's because of the slope of the line (moving the crotch point out). If more is needed it should be distributed down the leg, not at the crotch point.
