I don’t know about jeans, but if we are not supposed to wear clothes that the goyim wear, why do so many girls’ school uniforms incorporate plaid skirts/ jumpers from Catholic school uniforms? Once I was taking my kids to the park & saw a girl wearing a plaid jumper just like my daughter’s school uniform. I hurried over to say hello, but on closer inspection realized the family belonged to a local parish school.
Exactly what makes certain clothing “chukos hagoyim” and other clothing not? If goyim on Wall Street are wearing plain white shirts should Jewish men avoid dressing this way? If hats would come back should Jewish men stop wearing those?
