designer clothing is better quality, but the price is majorly marked up, so the value goes down.
Lets say
A calvin klein suit that costs $400 has a quality of 6 out of 10. The value is $66 for every point (400/6)
But the Baroni suit for $3000 which a quality of 10 out of 10, really has a value of $300 per point (3000/10).
So although the Baroni is better quality, the Calvin Klein has a much better value. It’s not worth it to pay so much more for slightly better quality.
