When in doubt, wear black.
I have the same problem the writer of this article had: no pressure at all to dress up. Which all fine when you’re in your twenties and don’t work in a bank. But now that I’m past thirty, even though I don’t intend to start wearing a suit, I think I should start dressing a bit more like my age. So that I don’t become one of those sorry middle-aged fools who dress like they’re not.
Anyway, nice to see I got the dark colors part right.
