Can navy Really Replace Black?

I don't know, can it? I find that I really prefer navy and it is taking a bigger and bigger place in my closet.  I retired my standby black balzer a few months ago and haven't replaced it because I just don't reach for it where as I wear my navy blazer at least once, sometimes twice in a week. navy shoes are hard to find and I just don't know whether classic black ever really goes out of syle. What do you think?"
