Stay away from v-neck tees that will show your cleavage, shirts that expose your back or showing too much leg. Some women will be wearing a black niqab, a face-veil that leaves only their eyes uncovered, while others will choose to only conceal their hair and a few will have their hair freely visible. If you choose to leave your hair free, make sure to thoroughly dry your hair before leaving your hotel, as wet hair is seen as sexual.
