Hey, of course there is nothing wrong with jeans – Calvin Klein was Jewish 🙂
My personal opinion is that there is nothing wrong with jeans. They are acceptable casual clothing nowadays.
Sometimes, I think people focus too much on external (non-halachic) issues, rather than working on mitzvos. To me it doesnt make sense to focus on “no jeans” (especially if its something that bothers someone) if someone is struggling mightily with another mitzvah.
Granted, there is nothing wrong with trying to dress better l’kavod Hashem, but I think its important to step back and ask “Is this l’kavod Hashem or for fake external recognition?” There are plenty of nice/tailored looking jeans that are respectful and there are plenty of dirty/ripped inappropriate black pants. Defining the color/material doesnt specifically make it a better garment.
One thing that I always wondered is there are plenty of families where the men will not wear jeans, but the women wear jean skirts. I really do not understand this. Can someone explain this?
