Interesting topic, Patience. I like to try new trends, but I am picky as to what I will try. My style is my style, and if the new trend is a complete opposite (like the whole glam-rock look) from what I wear and like, I will pass. So I will be adventurous about trying things within my style, but I tend not to mix a bunch of trends.
I do have a problem similar to Sarah's. When I put outfits together, I usually have to tone them down a little, to make them look "normal". As my husband reminds me occasionally, I don't work for a PR agency, or marketing department, or, gasp!, a fashion magazine. I work for a conservative tech firm, so I feel stifled by my own worry of looking "crazy". That really annoys me and recently I've started working through it by putting only one requirement on my office style and that is "professional" (not corporate professional). That gives me somewhat of carte blanche as long as I maintain the "professional" look.
