Nonsense. Suits look good because they have hundreds of years - literally - of refinement into something that flatters the human shape. You might as well complain about the cultural narrative of subconscious, instinctive body language.
For that idea to have a shred of validity, you'd have to explain why there is no such convergence in women's attire.
Suits are admired because they developed from the dress of the aristocracy and military and represent established wealth and power. They are a clumsy design, full of anachronisms, for example the buttons on the cuffs of a suit coat originate from Napoleon trying to stop soldiers from wiping their noses on their clothes. The second pocket on the right of many jackets is a ticket pocket introduced to hold an English gentleman's railway ticket in the time when rail was an exclusive way to travel.
If they really represented an evolved ideal way to make the human body look 'good' we'd all love to wear them and this debate wouldn't be happening.
This is correct IMO, because in my experience when I wear a suit or a tuxedo I feel sort of superior to others around me. This could have something to do with my personality or with the images that I have been fed or both. The idea has been implanted that "suits" == "good jobs" and "good jobs" == "good money" or "suits" == "obedience" and "obendience" == "climbing the success ladder". When I wear my black sweatshirt everyday to my engineering job, I wear it for comfort and it in no way make me look or feel inferior to other people.
Right - I wore a Brooks brothers suit to a courthouse to a speeding ticket hearing. I was treated with the utmost courtesy by the security guards who even held the door open for me, and once into the courtroom I was invited to sit with the other attorneys.
Obviously this wasn't because the suit made my body look great.
