Without specific examples - especially pictures - it's difficult to say much of anything definitive. We, as humans, can often use the exact same words to describe very different things. For me, personally, I express my personality through my color choices, fabric choices, and accessory choices. I'm very much a hat and suspenders guy - to the point that people notice when I go without a hat. For expressing my personal identity, I eschew trying to make too many statements with actual clothing pieces, as this reduces their versatility. Instead, I rely on my accessories for those statements - primarily via suspenders, pocket squares, lapel pins, cufflinks, rings, and necklaces. Still - whether I'm rocking University of Alabama branded gear, gear representing one of my favorite Sci-Fi universes (Stargate, Star Wars, Star Trek, Marvel, etc.), or callbacks to specific trips and memories like our anniversary trip to Hawaii - my overall look doesn't really change; my personal style is still my personal style.
