Do women need to keep their feet covered or not?

How much of her feet must a woman cover? Is it acceptable that legs and heels only be entirely covered while revealing the upper aspect of the foot, or should the whole foot be covered completely?Does the same rule apply when one is on Hajj? Must women wear socks while in the conditions of purity required for pilgrimage – ihram? Please clarify if a part of her feet may be left uncovered or if the whole foot should remain covered?

Are women obliged to wear a long robe – shar’i jilbab? If so, how long should it be? Are baggy pants which do not cling to the body to disclose her shape acceptable?

I am a newly converted Muslim woman who is a certified scuba diver. In order not to freeze when diving in the ocean, it is necessary for divers to wear wet suits and hoods. Such suits fit snugly to the body, so tightly that they do not disclose a woman’s bosom. Is it regarded as acceptable for a woman to wear such a suit? Being unsure, I have not gone scuba diving, an activity which I miss very much indeed!

In our very varied business world, which includes both sexes, is it ever permissible for a man to shake the hand of a woman?

I heard from a friend, who follows the Hanafi school of law, that when a man shakes hands with a woman his ablution – wudu – is nullified. Is this true?
