Many important people wear suits and, unremarkably, some of them are women. They are cool, calm, and certain. Unflappable in business and lunch meetings, they will not take any man's Trash Talk. This woman is a badass just from the aura she presents, this aura radiating from her power suit. Of course it isn't the suit that gives her power, but it sure doesn't harm the image she's trying to project that she is not to be messed with. On a man's chess board, she's captured the king.
This trope is for the powerful women demonstrating their prowess through an equally powerful suit.
Bonus points if their sheer presence intimidates men of a similar position.
Note that with the outdated image of actual '80s "power suits" — unflattering bulky tweed things with massive shoulder pads — the power suit referred to here will be a much more slim-lined, definitely fitted, and quite modern pantsuit, maybe even erring on the side of the traditionally masculine. Whilst characters in the shoulder-padded suits could be examples, it is dependant on how the work presents it: as these were typical office attire for any and all women of the period, to qualify it would require the distinctly powerful woman to be wearing a power suit and for no other woman in the work to wear one.
Compare Power Hair, likely to be paired with this.
