Always remember: Dress for the job you want, not the job you have. I can't stand to see the way some people dress for work these days. It's criminal. I am all for people looking good, but some people take it way too far. If anyone comes into my office in sneakers, or ripped clothing, or attire that looks like it belongs in a nightclub, I just can't take him seriously.
The above paragraph is under the title of How to dress and Groom for work. I cannot fully understand the meaning of the bold sentence in it.
Does it mean that the writer supports dressing properly at work or likes people who dress properly at work, but the way that some people dress is too strange and too far away from office dress?
How should I understand the phrase people looking good here?
