In the Orthodox church, it is a pious custom for women to cover their heads in church. If you follow this custom, here is a wonderful link for different ways to wear head coverings. They have even included step by step directions!
One of the reasons I like the styles shown on this page is that for women with little children, loosely fitted head coverings can be a challenge. The styles shown are this page are close to the head, tightly wrapped and away from the face. Very practical.
