I took these pictures some time ago with the intention of posting them here, but never got around to it.
Unless your business is breaking legs while collecting money, in your typical business setting there really is no room for a dark shirt. However in a clubbing setting (not the "Pay me or I will club you" Clubbing, I mean a night out on the town with some friends either male or female) it has a place as well as a more relaxed kids setting which is why we bought it in the first place. If in fact you are gonna wear that dark shirt then make sure you do some sort of contrasting color in a jacket so that there are clear lines between the jacket and shirt.
So if you are in the mood to chill out feel free to don that dark navy shirt with a pin stripe cotton blazer from Hickey Freeman or Armani Junior as shown below. In all cases shown with the contrast edge linen square to just throw a little brightness in. A tie will defeat the goal you are looking for. (Unless you do in fact break legs for a living...)
For some deep contrast go all the way out with this white/light blue cotton blazer from Hickey Freeman
