Well, Sorry at some places. Making it rain won't change anything. Heck, you may make it storm, or cause a earth quake to to happen or even a make Volcano to explode.

Some workplaces are so strict about dress codes, they just won't change for any reason. Especially large corporate bureaucracies. They have a crazy like beliefs that dressing in some way will help their business more than actual work will.

And going against those norms actually will work against you.
