I found this to be really insightful. It shows how the concept of modesty as it was kept in Judaism was very similar to what we see preserved in Islam. It was only in the last century that the Jews' traditional dress was changed to more closely resemble that of the Europeans. The author of the material also discusses some of the reasons for modesty and the true meaning of the Hebrew word Tzniut. It translated more accurately as subduedness, which is why modesty should be part of our submission to our creator.
