I wear mine almost all the time. Prophesying has also translated by some as testifying or to give testamony. Some will say that because prayer and giving testimony can happen at any point and place in time a woman should always be covered, if she is not asleep, or keep one about her shoulders. Some will carry one with them. These people will also hold to the "because of the angels" and "modesty" portions of covering as well. Others will only for service because of taking 1 Corinthians alone and it's context of assembly.
