I agree with everything that's been said.
Most members of this forum are dedicated dressers who've perfected an individual style with which they're comfortable, and therefore have little concern about what others think, or feeling different from the crowd.
I've been "dressing" for 30 years and there've been many days -- even as far back as college, law school and the early days of my career -- when some have thought me overdressed, or were intimidated by my appearance (which is more often the case).
But on far more days, at least two or three a week, even now -- and often by total strangers or passersby -- I'm' complimented on how well put together I am, or how I inspire them, or put a smile on their face, or bring a touch of elegance to an otherwise "slouching toward Gomorra" kind of world. Yet, no matter the reaction, I've always dressed for me and have never changed my style; you shouldn't either.
To me, each day presents a new occasion to paint a canvas with the many colors and textures in my closet. I dress in the manner that suits me for the plannned activity of the day, be it business, law, upscale or downtown, knowing full well that others will take note of my appearance (it has always equaled my professional reputation -- a tremendous one-two punch I might add). While I don't prance and preen like some self-indugent peacock, I also try not to hold back on what I feel is the look I want to project, or the colors or fabrics I want to combine; and I find that people admire that, even if they themselves lack the courage or creativity to pull it off. (I learned long ago that it is easy to be ordinary, but it takes courage to succeed. I've committed both balls to the latter.)
Granted, I do have a "down" or weekend look, that includes shorts, jeans, cordurouys or khakis, and that reinforces my "regular guy-ness," and undermines any suggestion that I'm some stuck-up or aloof prig. By the same token, however, you'll never catch me in a t-shirt (at least not out in public). Even when I wear jeans, my shirts will have a collar. Its my belief that the widespread preference for jeans and t-shirts (not to mention sweats) are what has ruined our sartorial culture. It has made us lazy and stolen our creativity, to the point where nowadays we let designers dress us. Indeed, most people now consider themselves well dressed simply if they're wearing the designer du jure. Its just tragic.
Back on topic: don't change your style per se, but temper it to place and activity. Its one thing to be one step ahead of everyone else, and another to be two steps ahead. Nothing will bring out the long knives quicker than people believing you're getting too far ahead of them; it makes them look bad (like the kid who always set the grade curve above your reach).
