No matter your cultural or religious background, you have some conception of what's okay and not okay to wear in public. For most of us, the rules are pretty relaxed: Cleavage is usually fine, but you should probably keep your nipples covered. Pelvage might be fun to spot on the red carpet, but it's not so practical for everyday life. For orthodox Jews, modesty is much more specific. Each creed or sect has its own strict clothing guidelines that pertain to fabric, colors, length, and cut. For most, that means elbows are covered; necklines stay high; long, conservative skirts are a must; and married women cover their hair.
