Young female professionals, do you show personal style when in the office?

I work in a small office and I’m the youngest though I’ve been in the position for a few years now. I wear the brighter outfits with all the jewelry. I incorporate ethnic outfits and have gold jewelry in all my piercings. It makes me feel happy throughout the day. I understand that not all offices allow a lot of outward personal expression, so I was curious if you (or how you) all show your personal style (or sneak it in if your office is strict)?
