There is nothing wrong with dressing and grooming well. The essay talks about people who spend substantial time and energy at fashion, at projecting an image. there are only two things really worth spending time on: 1) family and friends, and 2) your work, that is what you contribute to society. The second is helped by good grooming, neither is helped by being "fashionable" (unless your work is mostly image, like acting or other entertaining).
And the essay by PG is relevant because it points out that nerds are unpopular because they have more valuable things to do with their time than suck up. The "in crowd" spends effectively all its time sucking up to each other, and shutting out everybody worthwhile.
