Check back rise first
If the back rise is too long, extra fabric may pool under the seat. If it is too short, the pants may pull upward or create drag lines. Compare the back rise to pants that fit well.
Look at seat curve
Some pants are cut for a flatter seat and some are cut for more curve. If the curve does not match your body, fabric can fold, pull, or collapse even when the waist and hip measurements seem correct.
Check thigh ease
Too little thigh room can pull fabric upward and create bunching. Too much thigh room in a soft fabric can collapse between the legs. The best fit usually skims without grabbing.
Fabric matters
Thin linen, rayon, and very soft blends can wrinkle or fold more easily. A slightly heavier fabric, lining, or better drape can reduce bunching.
What to try
Try a different rise, curvy cut, trouser cut, or a fabric with more recovery. If the pant is almost perfect, tailoring the waist or seat may help, but not every crotch or rise issue is easy to alter.
