Eileen Fisher Black Crepe Modern Wide leg pants (I added pockets to them, LOVE!)
V or Scoop neck T-shirt long or short sleeve (depending on the temp)
Sweater (Usually a V-neck flat knit or a 'waterfall' type cardigan
Croc ballet flats or dansko clogs
some kind of scarf to give it some texture

I could live in this. I have several different pairs of EF pants in different widths and colors. 
T-shirts could be silk jersey or linen jersey but are usually GAP cotton
