I worked for almost two years for a shop that did custom dressmaking and alterations. Straight of grain is a real deal breaker. If you ever owned a garment that just never hung right it is because it was not cut on the straight of grain. The only other thing you can do is pull a thread and carefully cut where the thread was removed from the fabric. Good luck.
Another ripper here under those conditions! I'd also rip an inch or so wider if possible just to be able to rid myself of the distortions. This can be done by pulling those outer most threads on either/both sides. A little tedious but definitely have straight grain when you're done.
