That cami is a definite no-no. I'd say navy blue suit with a collared blouse in light blue, white, or matching navy blue. If you must go with a shell, make sure the neckline hits no more than an inch or so below the collar bone, and make sure it is in one of the above colors (no pink!). Also a big no on cream colored shoes or bag. They should be same color or darker than the suit, never lighter or brighter. Neutral colored hose, no colored hose. No perfume. Sparing jewelry (stud earrings, a professional-looking watch - leave the Mickey Mouse watch or Swatch watch at home). Muted make-up. Definitely closed toe, low-to-medium heeled shoes (no stilletos or peep-toe shoes). Make sure the shoes are polished and in good repair. It doesn't matter so much how expensive everything is as long as it is well-fitting and in good repair. Scuffed shoes or worn clothing will come across as lack of care on your part.
