anon1m0us: Please read the gemora. It clearly demonstrates that something as minor as the color of a shoelace can define Jewish clothing. And as the gemora says, the Jewish clothing were for reasons of Jewish modesty as well as for us to consciously choose to seperate ourselves from the Gentiles.
Yes, there is disticntive Jewish clothing and dress code today as there has been throughout Jewish history from the time we were in Eretz Mitzrayim.
