Here's the thing. If you're relatively junior, you don't want to give anyone ammunition to use against you. If you're a well renowned lawyer, banker, consultant, etc., you are more likely to be able to get away with wearing whatever you want. For someone who is junior, I'd err on the side of good taste and caution. Even if you can get by without it, looking good isn't a bad thing.
Nobody cares if Sam Zell walks into a business meeting in jeans because he's Sam Zell. A junior associate doesn't have that kind of pull. Especially for those times when you want to look your best, you should be understated and tasteful.
