Not at most enterprise companies. Maintaining an extra set of clothes is expensive, especially when they require frequent dry cleaning. I also found it was a hassle to 'match' all the time, I was called out for wearing a black shoes brown belt combo while running out of the house a few times.

Additionally, after work most of my friends have to change outfits to participate in social events. Business casual dress is useless, now I wear jeans, athletic shorts, and t-shirts to the office.
