How do you express your sims' personality visually? (decor, fashion, etc.)

Hmm, my Sims and their homes reflect just my own preferences. So, more or less same style always; laidback, casual, simplistic and natural colors. I'm a little set in my ways, probably in part due to my age, but I also have eyes that don't appreciate vibrant colors, and a brain that doesn't like too much clutter.
