The same as some of the other things recently being foisted upon the brethren:
Don't wear any kind of denim to the meetings.
Sisters at Bethel who work in public areas, i.e. lobbies, etc. must wear skirts never ever pants, even if they are doing manual type work. So I guess this means sisters picking apples must wear skirts while on ladders, as they are working in areas visible to the visiting dubs who might be offended. 'course we all know that this is an edict from Ted "J. Edgar" Jaracz the head of the Bethel CIA (aka Service Department) as he's afraid these sites will lead to a serious outbreak of wanking among the Bethel boys, and that would never do.
A long standing rule: Brothers at Bethel are not permitted to wear necklaces as this is a direct imitation of the homosexual community.
Bethelites are not to leave any Bethel home dressed to go in-line skating as this would be a major imitation of the world. If one absolutely must go skating, kindly hide that fact while in the vicinity of the Lord's house.
Should you have the desire to visit the Bethel facilities you must be dressed in appropriate meeting attire, never mind that you will be forced to walk your little feetsies off while taking in all the sites and passing contribution boxes at every turn.
