Your personal style can speak volumes. What's great about having your own personal style is that it can change over time but will always have your signature touch. Every gal has staple pieces in their closet that she can't live without. For me it is light weight sweaters and silk camisoles which are interchange able throughout the seasons. I am also a big fan of layering which is great for the times of year when the weather is changing (usual the end of each season).
What I do like to do is every so often buy something that is out of the ordinary for me and pair it up with something that I would usually wear. It gives my outfit a fresh twist but at the same time nothing too outlandish which would cause me to be uncomfortable. It's important always to be comfortable because no matter what you wear or how hot it looks fidgety movements and looks of uncertainty can ruin everything! Your style should also be right for you and your body type. Unfortunately we can't all wear what's hot just because it is the latest.
I think a personal style should always look polished and for the most part timeless. I truly admire Sienna Miller's style she can glam it up and at the same time has an edge that is all her own. Her clothing line Twenty8Twelve is a true example of her style.
I think it's key to always be yourself and don't be afraid to step out your comfort zone from time to time.
