Well, I don't know about your church, but at my parish, we have this sort of unspoken rule that one dresses discretely, modestly,humbly, for the divine services, so as not to be a source of temptation and not to draw attention to oneself, but rather to ensure God gets all the glory. For this reason, the women all cover their heads well for the divine services and often wear a jacket or sweater and long sleeves and long skirts. All the churchly men as well appear to dress quietly, modestly, for services. I have rarely noticed anything otherwise, and thankfully one thing our parish is blessed with is good order. At times, as a woman, I do find myself distracted by what some woman is wearing if it is immodest or flashy(we stand in segregation, so for this reason I notice the women more, I think). This is a good chance for me to try not to judge, to avert my gaze, and to focus my heart on worship and prayer rather than other things.
