Wow Crumpet! Bad info...no wonder you were confused. As far as I can remember, "community standard" was the official issue. I have heard of individuals linking the crossdressing issue, but I do not know if there was anything "offically" printed. The whole crossdressing thing doesn't hold water; when that scripture was written, men wore dresses and women wore (harem)pants!!!
However, I would LOVE to see that enforced...make the brothers wear dresses!!!!!
