Add another incredibly inexpensive staple to the mix and pick up this Pleated Mini from Old Navy.

The skirt, which is now $12.99 down from $29.50 can take you from the office with a simple blue button down and blazer (albeit a laid back workplace that lets you wear minis) to cocktails with a pair of strappy safari-inspired brown shoes, a tank top and the same old blazer— with the sleeves rolled up, of course.
