I am editing my original post, because I have thought of a better way to frame my question.

The facts: I am a 26 year old executive in the healthcare environment. The office I work in has a dress code policy of "business casual". My coworkers (both below me, above me, and in similar positions) wear a variety of outifts. I have listed a few examples below:

A/P Coordinatior is in capris and a volumnious top
CFO (male) is in khakis and a polo
CEO is in chinos and a patterned 3/4 sleeve jacket
Another staff member is in bermuda shorts and a t-shirt.

I would like to look polished, professional, and pulled together while maintaing a youthful edge. Can you ladies suggest what pieces I should incorporate into my wardrobe? Do you have a favorite outfit from a YLF member that you think would work in my situation?

Many, many, many thanks.
