Does adopting new trends every season help, or hinder, the development of a personal style?

If fashion has shifted to the point where choice reigns supreme, there is more than a little irony in my thinking I need to incorporate at least some of the current "trends" into my wardrobe to stay "updated". If none of the current trends get me excited (ugh to pastels, pointy-toed flats, baggy pants, and animal/snake prints), can I just sit on the sidelines basking in the knowledge that maybe I'm moving towards developing that elusive commodity--a personal style? Or will a devotion to fitted, straight-leg pants and a love for solid jewel tones just be the start of a slow descent into Frumpville?

I can see how experimentation and a willingness to try something new can expand horizons, but can there be too much of a good thing? Can continually trying out new trends every season end up just being confusing (and expensive) instead of liberating? Is there a time limit to how long you can sit on the sidelines?

I'd love to hear your thoughts as I sit here trying to make up my mind about what to do with this season's trends.
