True Left

Thank you for admitting that you are a Westerner. Here is a photo of Richard Spencer in your colonial masters' clothes as a present for you:

Let's look at this picture that you posted:

Notice how similarly the woman on the right and the man in the centre are dressed. This is sartorial low sexual dimorphism. This is superiority.

Sure, it could be neater, and by the 70s it had already become neater while retaining the reduced sexual dimorphism:







(Note in particular the bell bottoms, which are designed to give the impression of ectomorphy. In contrast, the reinforced shoulder and lapel of Western men's suit jackets are designed to give the impression of mesomorphy.)

And the 80s-90s saw the rise of tracksuits, which continued to retain low sexual dimorphism while further trimming away Western geometric elements:





"Those such clothes not worth for use during work"

Tracksuits are perfectly practical for working in.

(Finally, in the original topic I had already ridiculed neckties, but thank you for providing additional pictures to support my thesis.)
