If you pull out one horizontal thread (as close to the cut edge as possible) it will tell you whether the fabric is printed crooked or wound on the bolt crooked. If it is printed wrong the only solution is to fussy cut and hope for the best in terms of grain distortion. If it is wound on the bolt so that it is crooked, pressing on damp of wet yardage using a straight edge to assure accuracy will straighten it. That is time consuming but worth the effort. I would not like to include a fabric like that in most cases.
