Not to resurrect a dead thread or anything, but it never fails that when you complete a nice wardrobe for business attire, your company will switch to business casual. Then back again.
Seriously, I worked at one company that was BC, and I finally just went out and bought a bunch of nice polo shirts (Nautica, Claiborne, Ralph Lauren). Within two weeks, they announced that the office was going business.
Then, I went to a company that had business attire, and I decided to go ahead and fill out that portion of my wardrobe. Bought ten dress shirts and about the same number of ties. Sure enough, they then announced business casual. At least most of the shirts I had from the previous purchases were still viable. I occasionally wore ties anyway just because I had them.
What a pain.
Now, I wear Air Force blue, and there's no danger of that being changed.
