Clothing – Modern permitted?

Igros Moshe (YD I #81) Question Concerning  modern clothing in which there is no difference in America between Jewish and non Jewish clothing. Does a person coming from Poland which has distinctive Jewish clothing and his children born in America have an obligation to wear the clothing that was worn in Poland because of the prohibition of wearing non Jewish clothing? What if the father already has changed to modern clothing even though that was prohibited? The universal practice is to wear modern clothing, even very pious individuals. Is this permitted?Answer The Maharik says that there is not any obligation to wear different clothing than non Jews unless their clothing is immodest or arrogant.  Similarly it is prohibited if the modern clothing is worn soley in order to appear more like non Jews or there is a concern for idolatry. .  This is also the view of the Remah. The Maharik indicates it is permitted even for the slightest benefit or honor That is why doctors typically wear a special garment and it is not consider prohibited as a non Jewish garmemt since there is a benefit. In conclusion there is not the slightest prohibition wearing normal contemporary clothing in America. . Furthermore who says that the Non Jews wore these garments originally and only later were they worn by Jews? Perhaps initially everyonre wore them and thus even the Gra would permit them and it would be permitted also for those that came from Poland as they would not be considered non Jewish clothing
