The Suit… and the attendant pollution it brings

Newsweek proclaims that the Suit is back in fashion:

To me, Suits mean tight collars, sweating and discomfort, huge expense, and, DRY CLEANING!

I wonder what the environmental cost is to maintaining a suit(s). I googled "dry cleaning, pollution" and after reading several sites, including the EPA site, the conclusion I came up with is that even the most well-meaning, environmentally-conscious dry cleaner will still pollute the environment.

So why wear a suit? Why wear a uniform?
