I don't doubt your statement, nor am in denial as to the versatility of what can be done with navy. Nor do I think that it cannot, in and of itself, be interesting. However, my use of the word interesting has less to do with "not simple" or anything having to do with the clothing itself and more to do with "something that keeps my interest." Given that I have no other impetus for determining a personal mode of dress beyond that I find it interesting, doing something else seems counter productive. I don't deny that what interests me can change in the future nor do I disagree that I am at a relatively early stage in my sartorial investigations. I think refinement and mastery are exceedingly interesting, and can't wait to get there. I don't think I'm there yet though and when I do get there, without some compelling need otherwise, I don't feel the need to get there through things I don't like and don't hold my interest. There will be plenty of time for Navy to hold my interest down the road and I will address it when it is more pertinent.
It is entirely possible that five years down the road I will find this to have been a mistake. However, I make that sort of self-awareness a personal point of focus, and I don't predict that will be the case - hence why I went ahead and bought it. As always though, I could end up being wrong, which is in and of itself something I find interesting.
For what it's worth, I like the pattern of your suit and would wear it myself. I dont know what stage you're in or if this is your "1st" suit or just your 1st custom suit. Either way, if it fits you well then you'll be alright. The color is suitable for any daytime business and is interesting because it is not navy/charcoal/generic pinstripes.
