When I did my job interview back in 1991. I did not don a suit since I could not afford it. But, I donned geometric outfit instead of organic one.
Geometric shapes look as though they were made with ruler or drawing tool. The square, the circle, the triangle, the rectangle, and oval are the five basic geometric shapes all components of formal attires.
While, organic shapes also called free-form are not regular or even. Their outlines may be curved or angular, or they may be a combination of both, to make free-form shapes like those of informal attires, but used by most celebs in their custom made outfits especially musicians.
So, for ladies, you don’t have to don skirt-suit; a basic shift or styled shift dress in blazer above can score top marks.
