Are you wearing it with the waistband level from front to rear? It looks as if it may be dipping down just a bit in front, which can force the front pleats open. It only takes a little off-kilter (ha ha) for the pleats to get out of parallel and start going every which way.

Try hiking the waistband up an inch in front and see if it makes a difference. If not, let us know, and we'll keep working on it with you!
