Crotch point fitting

Hi everyone:
I'm working on a costume and the pattern fits perfectly except there's lots of excess at the crotch in the front and back, going in different directions. See the pics below:

In the front, I've pinned an excess of 1" total for each leg, which radiates from the crotch curve down toward the knee.


In the back, I've pinned almost 3" total for each leg, with the excess running vertically.

If I subtract these excesses from the crotch point towards the hip, I will have either a very short curve or no curve at all. How can I fix my patterns?

Thanks!
