Hmm, for me it's a real mix. I have statement pants: wide-legged, plaid, polka-dot. I have statement shoes: red leather ankle boots, glitter-covered mary-janes, silver mary-janes. My burgundy lace-up boots always get people's attention, though I don't consider them to be "statement" boots in the traditional sense. Some of my accessories -- hats and scarves -- can make a statement. My tops tend not to be particularly statement-y, except for the occasional graphic tee (I've found that a cute critter on a tee is guaranteed to get comments!). I have a couple of statement toppers, but find them a bit harder to wear.
I do not really look to jewelry or eyewear to make a statement. I only wear sunnies, no prescription, so can't rely on them as an outfit component. And I'm picky about jewelry, preferring sentimental pieces with a story; I have very few pieces that I wear for looks alone, and the ones I wear most often tend to be pretty quiet.
