So why is it we wear kippot and yarlmukes ?

some say In Judaism, men cover their heads as a sign of respect, a gesture in deference to God - which is why in most sanctuaries and at many religious events, you'll see men or some cases women, wearing yarmulkes, referred to in Hebrew as kippot, or skullcaps. The more religious Jews are more likely to wear a head covering in public at all times. Done out of modesty and so to avoid attracting attention from other men, Orthodox married women might wear a scarf, a wig or a hat. A leading scholar at Brandeis University near Boston says that for men, in particular, "head coverings have become a marker of what kind of religious Jew you are." This, he says, is especially true in Israel. Hasidic men, the strictest adherents to orthodoxy, can be identified by black hats, for example. Married Hasids in some sects, however, might wear large, fur-brimmed hats called shtreimels on holidays, the Sabbath or during special occasions. He explains the type of hat and the color or kind of fur are all indicators of sect and religious stature. Likewise, particularly in Israel, the kippah a man wears will tell a story. A black velvet or black cloth skullcap or kippah and yarlmukeh signals traditionalism, He says. Modern Orthodox men, however, are more likely to wear knitted kippot. The smaller the kippah, the more modern and even liberal he is. Indeed, beyond serving as a religious marker, kippot in Israel provide glimpses into political stances. Jews who are part of the controversial settler movement, for example, can often be identified by their large knitted kippot.
