Do you have any role models 0n workday style?
Who are they? 
What do they look like?
What do you wear to work?
I realize that I have lots of ideas of what I don't want to look like as I develop professionally, but I'm not sure I have any ideas of who I do want to look like.
At my last job I worked with a woman who has the sense of style I always thought I would acquire when I grew up and bought new clothes-- she wears unstructured jackets and raw silk jumpers and loose clothes of purple or green patches purchased from fair trade booths. She wears no make-up, her hair is still long in her forties, and her comfortable shoes rarely coordinate with her outfits (her style somewhat like JD at KBS). It works, but it's not me at work.
In my department here, I've got two short foreign women who end up looking like they don't care, even though I think that both do, a woman who looks great at fifty but wears nylons and sensible heels every day and lots of coordinating synthetic skirt outfits, none of which I am about to do. There's a professor who dresses more like I do, but to the point that I can't tell if she has any style either.
Thinking of the women at KU, well, Maria has distinct style, but it is nothing that I am going to emulate. HA sometimes has a look that I want to avoid-- the little practical scientist lady. Actually, my size (and my smile and my penchant for large necklaces and my unwillingness to cut my hair) make me unable to pull of a "very basic clean and well groomed science lady" look.
So who do I look to?
