C.M.R.I. hasn't a code about how long or short a womens hair should be, mine is long, but I usually wear it pinned up.
Women must be modest, no pants, dress or skirt must cover the knees when sitting, the longer the better. Low cut tops are to be avoided always.
Once in a while we have a new comer dressing improperly but since they are guests people overlook them, however the usher willl offer the women a loaner veil for their head.
