Style intervention

Someone needs to call Tim Gunn on my behalf.  I seriously need a style intervention. 

I caught a glimpse of myself in the mirror at school the other day.  I swear I was starting at a reflection of my mother.  Don't get me wrong.  My mother is a lovely woman and dresses nicely.  I was unaware that my style has morphed into hers.  I'm about to turn 40, not 60.  Tim (my Tim, not Tim Gunn) asked me if I didn't want to look like my mother, then what did I want to look like.  And here's why I need the big Gunn.

I was to be comfortable and neat and not look like a slob.  I don't want to look frumpy any more, but I don't want to be a fashionista.  I would rather be timeless than timely.  I need to look somewhat professional, but not in a suit or a skirt.  Oh, and I'm cheap.  How do I accomplish all this?  Clearly, I am not able to do this on my own.  I'll accept help from any basic cable style guru at this point.
