You could have quoted 1 Thessalonians 5:22, but that would have worked against you. So, you misquoted John 7:24. If things are as they appear, then judging by appearances is righteous. But, that's not what Jesus meant. Jesus meant not to judge by the appearance of the law (apart from righteousness), not the appearance of someone's behavior (which includes attire). Try reading the context.
No, I don't think I did misquote. The whole thing, 21-24 Jesus answered them, “I did one miracle, and you are all astonished. But because Moses gave you circumcision, you circumcise a boy on the Sabbath (not that it is from Moses, but from the patriarchs.) If a boy can be circumcised on the Sabbath so that the Law of Moses will not be broken, why are you angry with Me for making the whole man well on the Sabbath? Stop judging by outward appearances, and start judging justly.”
Attire, including the standards by which something is considered aesthetically pleasing, depend on the context of cultural convention, they are the equivalent of what is from the patriarchs. What clothes are what depends on not the objective law of God but on the people and times where, in this case, is the Anglo-American culture. Modesty, especially in terms of sexual suggestiveness, are objective seeing men and women generally look for similar things in terms of attractiveness and lust after the generally same sorts of areas. Modesty is in response to lust, there's actual law in that. How you do it has a lot more cultural influence behind it.
This has nothing to with "upper end clothes". It has to do with wearing slacks instead of jeans or shorts. It has to do with tucking in a shirt. It has to do with dressing to show respect, because you have respect. Rather than dressing like a slob because you're a disrespectful, self-centered consumer.
I don't judge anyone by what they wear, except to the extend that what they wear tells me who they are. And, our culture and freedom suffers for it.
And on that 1 Thessalonians jab, observe everyone, the apparition of evil - never has there been a more terrible display of gluttony, sloth and sin.
Oh, wait, he looks like a pretty normal young man. B-b-but he's wearing jeans and hasn't tucked in his shirt! How could anyone wear something so immodest in a church?
I mean, I don't mean to mock but this is laughable. Those people in the line at the job fare? They were dressed fine. I would do a bit more at a job interview but if their resumes checked out and the prior employment referees gave good reviews than why not?
Oddly enough, one time where I mistook the thread on the women's forum and clicked on that thinking it was here, I read an interesting opinion suggesting that dressing up as you entail is less modest than just more everyday, comfortable wear.
You know, if I want to know who somebody is, I ask them to be quite honest. To be quite honest, the Jesus who surrounded himself with children, tax collectors, beggars and prostitutes probably would have had the same approach.
