Any pants that don't need dry cleaning will look like a Jiffy Lube uniform after a few washings.
Corporate is about how you present yourself. Sure, you "can" wear polos and dockers. If so, I hope you like your current job because the guy who gets the better job will have made a better impression.
All IMO, of course.
