Bias cutting has a reputation for being unpredictable, and a lot of that reputation comes down to this one layout mistake that's easy to make and not always clearly explained.
The problem is that parallel pieces all pull in the same direction, with nothing to counterbalance that pull. The result is a garment that twists, with side seams that drift and look off.
What you want instead is perpendicular placement: front piece on one bias diagonal, back piece on the opposite. Those two directions work against each other in exactly the right way, creating balance so the finished garment hangs beautifully and the side seams stay put.
