Wearing Black and Blue together?

[Corporate Hipster]

I say you can do it if it looks purposeful. And make sure it's navy blue with a dark black.
Anyone dare to disagree?

only problem is when the black isn't black enough and the blue is too dark, so it starts to like like you're slightly colour-blind and can't see your gear has faded. When done right its killer.
