Such an interesting post and very interesting responses! I was nodding along with Kkards especially. I tend to think of lots of concepts along a continuum, rather than starkly dichotomous, so I would put unique on one end (style that is completely one of a kind, which is almost impossible to achieve, unless you are doing something very exceptional and having some clothes custom made, someone like Iris Apfel, e.g.?) and ordinary on the other end, with lots of space between these two poles to land on in terms of one's style.
The pesky issue of one's environmental norm is really interesting too, so what's ordinary in one context might be unique in another. I remember returning from college the summer after my first year and going to my hometown's 4th of July celebration. I was dressed in a way that was totally "normal" for my anything goes college setting, but I stuck out a lot (to the point where people were staring and mocking me, LOL) in my small rural town.
Then there is one's reference group (the people we compare ourselves to, our reference point, which we tend to do automatically). How much to fit in, how much to reject, how much to compare? As a professor, my reference group tends to be other professors, and with that comparison, my style is typical in some ways, not-so-typical in other ways, which I am comfortable with. But if my reference group were 20 year old college students, or "influencers" on social media who are wearing borrowed clothes and trying to look unique, then my style would seem out of touch.
ETA: I mused so much I didn't even answer your questions :). Here goes: I enjoy expressing myself through my clothes and enjoy tickling my own fancy, but I don't consciously set out to wear something "unique." Nor do I strive to totally blend in and wear something "ordinary." My goals are different than either of these, and somewhat dependent on what the outfit is for. Since a big part of the fun for me is putting different items together in new ways, I wouldn't ever wear a whole outfit straight off of a mannequin.
ETA x2: I totally reject the criticism of "trying too hard" and it's never something I would say to myself or anyone else. To me, it seems like something people say to try to cut down someone else, or mock them, because they don't understand what they are wearing, it's unique or stands out from the environmental norm (and they are policing those norms, so anyone in violation is going to get called out), and/or it makes them uncomfortable.
Okay, I am done with replying now :).
