Need more info!
I don't work in an office but, as a teacher in a secondary school, I have to be fairly traditional.
What I wore this week (if I can remember!):
Monday - black and white striped just above the knee dress from M&S, worn with white t-shirt underneath, black cardi over (all M&S) with Autograph bare leg look tights and black ballet flats.
Tuesday - black pencil skirt, grey silk top (tucked in), black linen mix jacket, tights as above (but clean ones!) and black Mary Janes.
Wednesday - grey high waisted pencil skirt, grey silk top tucked in (different one!), pewter cropped cardigan, grey wedges.
Thursday - fitted black and white floral dress, black cardigan, ballet flats.
Today (it was cold this morning!) - black over the knee skirt, black tights, burgundy top, rose cardigan, ballet flats.
Nearly everything from M&S Ltd Collection or Autograph, Gap, Warehouse or old stuff from Principles.
